Hello Devs! 👋 I'm following the Akshay Saini DSA course, and today was all about warming up with JavaScript fundamentals. Here's a quick summary of what I learned 👇 🔰 Course Introduction “Don't just learn DSA for interviews. Understand the concepts deeply — interviews will become easy automatically.” He also suggested maintaining our own notes or copy — writing things down helps a lot in revision! 🔥 JavaScript Basics Refresher This simple line prints text to the console. The value "Hello Laxman" is a string — in JavaScript, strings are enclosed in double quotes ("") or single quotes (''). 2️⃣ Data Types String → "hello" Number → 10, 3.14 Boolean → true, false Object → { key: "value" } Array → [1, 2, 3] 2️⃣ Variable Declarations: let vs const let a = 10; → allows reassignment (a = 20 is fine) const b = 15; → does not allow reassignment (b = 20 will throw an error) We can access them like: console.log(a); // Output: 10 3️⃣ Arrays let arr = [1, true, false, [1, 2]]; Accessing values: arr[0] → 1 arr[3][0] → 1 (nested array access) Arrays store data as index-value pairs, starting from index 0. 4️⃣ Objects let person = { name: "Laxman" }; console.log(person.name); // Output: Laxman 📌 Wrap-up I’ll be sharing my progress daily. Feel free to connect or follow along if you're also on this path! Until tomorrow, happy coding! 🚀  ( 4 min )

In the last post, we talked about stack, stack trace and symbols, and how to make use of these. I've mentioned that in future i would like to focus on replacing GCC __builtin_return_address() with frame-pointer unwinding and improving symbol lookup performance with binary search. So, lets begin. Frame pointer unwinding is a method which can be used to get backtrace (iterate through stack trace). It assumes that every function has stored the frame of previously called function using frame pointer (in our case ebp register, because we're on x86 - or for example rbp on x86_64, fp (aka x29) on AArch64, etc.). This creates a linked list of frames, where each frame points to the one below it (i.e., the caller's frame). That allows us to traverse the call stack in a straightforward way — just by …  ( 4 min )

The performance of expertise is dying. What's replacing it is quieter, more powerful—and finally scalable. 🪞The Collapse of Performed Expertise Decks became sacred texts. Buzzwords became armor. Trust was simulated—not earned—through polish, posture, and presentation. It worked. For a while. But in the shadows of boardrooms and Slack threads, something else began to move. Decision-makers started saying what they’d never say out loud: “Smart, but didn’t move anything.” The performance collapsed. 📉 What’s Dying—and Why Here’s the fracture point: Firms sell polish. Fractionals deliver pattern recognition. Firms simulate trust. EaaS practitioners embed it. Firms extract. Fractionals transfer. Clients no longer want potential. ⚙️ The Rise of EaaS Expertise-as-a-Service is not a trend. It’s a …  ( 4 min )

Machine learning, a term we hear everywhere these days, has become one of the most transformative technologies of our time. Chances are you have at least once wondered what machine learning is and how it works. Machine learning (ML) is a fascinating domain that allows computers to perform tasks typically related to human intelligence, actually, ML is just a branch of artificial intelligence where systems “learn” from data to identify patterns, make predictions, or even generate new content, but are you still trying to figure out why is it called "machine learning"? Well, the process of machine learning ensures that machines do not need to be programmed for every single scenario, they just “learn” from big amounts of data, just like how humans learn, for example, when you open your favorite…  ( 6 min )

Problem Statement Given a circular integer array arr[], the task is to determine the next greater element (NGE) for each element in the array. The next greater element of an element arr[i] is the first element that is greater than arr[i] when traversing circularly. If no such element exists, return -1 for that position. Circular Property: Since the array is circular, after reaching the last element, the search continues from the beginning until we have looked at all elements once. Input: arr[] = [1, 3, 2, 4] Input: arr[] = [0, 2, 3, 1, 1] 1 ≤ arr.size() ≤ 10^5 To find the next greater element for each value in a circular array, we need to determine, for each number, the next number in traversal order that is strictly greater than it. We use a stack to keep track of the indices of element…  ( 5 min )

If you are in the web development world, you already know that TypeScript compiler will be migrated to Go (unless you've been living under a rock). But why should you care about it? Well the answer is simple, the typescript compiler migration to golang will improve your developer experience. In this article I'll skip the stuff you have already seen and go straight to the point. People keep claiming “oh it's 10x faster!” but let’s pause. What does this actually mean for the folks writing code every day and is there a catch? TypeScript itself isn’t changing. You’ll still write code the same way. What’s really changing is the compiler. You may know it as that strange thing that turns your TypeScript into JavaScript so browsers and servers can run it.

Mistral AI has unveiled Magistral, shifting the focus from AI that simply delivers answers to one that explains its process. This model promises to make AI more trustworthy by breaking down complex tasks step by step and supporting multiple languages. Magistral is Mistral's first reasoning model, designed for multi-step logic rather than just generating text. Unlike traditional models that memorize and respond, it mimics human thinking by working through problems in a structured way. This approach ensures outputs are verifiable and reliable, which is crucial for fields like finance and healthcare. The model uses chain-of-thought training to handle queries. It divides a problem into smaller steps, processes each one, and then presents the full reasoning alongside the answer. For instance, a…  ( 4 min )

{ Abhilash Kumar Bhattaram : Follow on LinkedIn } For decades, Oracle DBAs have thrived in the command line. We've whispered arcane incantations into sqlplus, summoned backups with RMAN, and tamed complex clusters with srvctl. We know our tools, we trust our scripts, and above all—we speak fluent terminal. But in this new era of cloud, the command line hasn't disappeared. It's just evolved. Enter the OCI CLI—Oracle’s official Command Line Interface for Oracle Cloud Infrastructure. To the uninitiated, it might seem like just another cloud tool. To us? It's sqlplus for infrastructure.

🔷 Java vs JavaScript: What’s the Difference? 🤔 As a developer diving into both Java and JavaScript, I often see beginners confused by their similar names. But in reality, they are two completely different technologies serving different purposes. Let me break it down: ✅ Java — A powerful, object-oriented, general-purpose language. Used for building robust backend systems, Android apps, enterprise solutions, and more. Runs on JVM, compiled, and strongly typed. “Write once, run anywhere.” ✅ JavaScript — The language of the web. Lightweight, interpreted, and primarily used for frontend web development to make websites interactive. Can also power backend (Node.js), mobile apps, and even desktop apps. Runs in browsers and is dynamically typed. ✨ Despite their names, they are not related — JavaScript was named during the Java hype in the 90s to attract attention. Both are incredibly valuable to learn depending on what you want to build — and as a Full Stack Developer, mastering both opens up even more opportunities! 💬 What’s your favorite — Java, JavaScript, or both?

Let’s face it — when someone says “design patterns” in a tech interview, most of us immediately panic. "Ummm... I think, I used a Factory pattern once… maybe? Probably? Singleton I did. When? I do not recall exactly." The truth on the other hand is you’ve probably used several design patterns already, without knowing it. Design patterns are just common solutions to common problems in software design. They're like recipes. They don’t live in libraries. You don’t npm install design-patterns. They live in your logic and architecture decisions.

Why I Built use-s-react I've always liked React's functional style, but when it comes to managing state in the application, things get complicated and whatever alternative you choose, you end up writing the detested boilerplate. useState is great for local values, but managing shared state across components? That often meant jumping to useContext, Redux, Zustand, or other more complex tools. It's not just boilerplate, if you want to use a third party library, you also end up having to learn new concepts or approaches to make use of it. But in many cases, all I wanted was: a simple way to manage local and global state without all the ceremony. useS is a React hook for managing local and global state through a simple, unified API. It's powered by useSyncExternalStore under the hood, ens…  ( 6 min )

Hello, while writing with JavaScript, I encountered the following shiftRight() function. The final section clears the last character with a dash. This is because it is overwritten.

Web UIs often look like magic compared to native apps. I used to think the web had some mythical language behind it. Turns out? C++ engine example Chrome, running CSS, JavaScript, and HTML. The elegance doesn’t come from the syntax, but from the ecosystem. Web dev moves fast because the market demands it. Here's the fun part: almost every low-level language can hook into C or C++. Golang is no different. You don’t need a miracle to build beautiful GUIs in Go. Just wire up a lightweight webview and let Go in the backend do what it does best: be fast and powerful.

At some point, your project outgrows the usual patterns. It starts to split into mini-projects, not big enough for separate libraries (which are a pain to manage), but too isolated to share logic cleanly. But the real headache begins: when two or more of these mini-projects need the same behavior. Which is a full-blown object with state. The answer? Singleton structs, objects you create once and reuse across your app, with state and all. Hoist it. Literally. It’ll save you from half the complexity. I hit this exact problem while working on my agentic project. The modelservice embeds a tiny utility server as a webhook for a browser extension.

So what even is MCP? MCP, short for Model Context Protocol, is a protocol designed to enable developers and applications to provide context to agents & large language models (LLMs). MCP Specification includes support for a number of different "context" primitives that can be provided to an agent, including prompts, tools, and resources, Read that, understand that, and then forget that. The primary use-case for MCP, and the only one that popular MCP clients like Cursor, Windsurf, and Claude code support, is tools. The primary use-case for MCP right now is to plug tools (and therefore new capabilities) into your agents in a low-code, low-configuration way. Here's an example of my favorite high-impact use-case for software development: Puppeteer's MCP server. By adding a simple JSON confi…  ( 10 min )

Are you a legacy React developer? Have you heard of the chronicles of a once-mystical creature 👾 known as class based components in React? After spending so long exclusively in the React ecosystem — with only brief forays into Vue.js and Angular — I almost feel confined, as if under house arrest. It's as if React has become a pandemic and developers its captive patients.

Writing clean React code isn't just about making things work — it’s about readability, maintainability, and scaling your components. Here’s a simple visual cheatsheet that highlights best practices for building better React components. ❌ Bad: ✅ Good: 💡 Use meaningful, descriptive prop names. ❌ Bad: {!isLoading ? : null} ✅ Good: {isLoading && } 💡 Use early returns and avoid nesting where possible. ❌ Bad: /components Button.js Card.js Modal.js ✅ Good: /components /Button index.tsx styles.module.css types.ts 💡 Organize by component, not by file type. ❌ Bad: const fetchData = async () => { const res = await fetch(...); const data = await res.json(); setState(data); }; ✅ Good: import { getUserData } from '@/services/user'; const user = await getUserData(); setUser(user); 💡 Keep logic in services or hooks. Components should be mostly UI. ❌ Bad: useEffect(() => { window.addEventListener('resize', handleResize); }, []); ✅ Good: useEffect(() => { window.addEventListener('resize', handleResize); return () => window.removeEventListener('resize', handleResize); }, []); 💡 Always clean up your effects to avoid memory leaks. Clean code in React isn’t just for you — it’s for your teammates, your future self, and the community. Refactor small, commit often, and prioritize clarity over cleverness.  ( 3 min )

In May, I published a detailed technical breakdown of a fatal, platform-level crash in AWS Lambda — a Node.js function inside a VPC making outbound HTTPS calls that would silently crash after returning a 201. No logs. No errors. No stack trace. AWS eventually reproduced it themselves. This post isn't about the bug. It's about what AWS did next. Even after AWS reproduced the crash using their own test code, their response wasn’t engineering. It was damage control: They blamed our code They revoked a previously granted $4,000 credit They silently billed our founder’s personal card They filtered technical escalations through sales They offered the credit back — this time as a settlement tied to silence And they asked our CEO, off-record, not to publish We published anyway. Culture, Not Code This isn’t a teardown of runtime behaviour. That’s already done. This is about support failure, accountability avoidance, and AWS’s cultural instinct to deflect rather than own fault. If you’re building serious workloads on Lambda: read this. Because when support fails, logs go dark, and engineering won’t speak — you are on your own. Read the full follow-up post here  ( 3 min )

Why an Information Security Policy Is Crucial An Information Security Policy plays a vital role in an organization’s overall risk management and cybersecurity strategy. It provides a structured and standardized approach to identifying, mitigating, and managing the risks associated with data and information systems. By setting clear expectations and guidelines, the policy ensures that all employees, partners, and stakeholders understand their responsibilities when it comes to safeguarding sensitive information. One of the key reasons this policy is essential is that it fosters a culture of security awareness across the organization. When employees know what is expected of them and receive proper guidance, the chances of accidental data leaks, human error, or negligent behavior significant…  ( 4 min )

It Started With an Email Subject: “Congratulations! You've Just Won ₦750,000 in the Dangote Empowerment Grant!” I almost laughed when I saw it in my inbox.

"Sometimes it’s not about what you add, but what you protect." In my internship journey, I revisited a crucial lesson that every developer (especially full-stack ones) should hold dear: never trust the frontend when it comes to security. 🔍 The Problem It felt secure... until I asked myself: Answer: They might just bypass all our hard work. 🔒 The Solution: Backend Enforcement 🧰 Backend Guards and Decorators custom guards and decorators in NestJS: ts // Example: Role Guard @Injectable() export class RolesGuard implements CanActivate { canActivate(context: ExecutionContext): boolean { const request = context.switchToHttp().getRequest(); const user = request.user; const requiredRoles = this.reflector.get('roles', context.getHandler()); return requiredRoles.includes(user.role); } } // Used like this: @UseGuards(RolesGuard) @Roles('admin') This simple logic ensures that even if someone sends a forged request, they won't pass unless the role matches. 🔁 Workspace Validation A @WorkspaceMember() decorator Logic to confirm the user is part of the workspace they’re acting on AuthorizationService with reusable checks 🧪 Testing Can an admin delete a document? Can a lawyer access a case from a different workspace? (They shouldn’t) Can anyone else invite users to a workspace? 💡 Takeaways Frontend is UX. Backend is law. NestJS makes it easy to build modular, reusable security logic Good security is invisible to the user — and obvious to the developer I now have a deeper respect for backend checks and how they actually protect users ❓ Today’s Question I’d love to hear how others handle authorization at scale.

Introduction In this second part of the series, we’ll build a simple yet secure login page — entirely without a backend. Using only browser-based cryptography, local storage, and Redux, we’ll create a seamless login experience. Here’s what we’ll implement: An in-memory secret key store using Redux. Protection for the main vault page based on key presence. A login form that authorizes the user via a master password. The full project is available on GitHub. You can play with the completed app here. To securely hold the cryptographic key during a session, we use Redux to store it in memory only. This means the key disappears when the app reloads — which is exactly what we want for handling sensitive data. Here’s the vault slice: import { createSlice, type PayloadAction } from "@reduxjs/tool…  ( 6 min )

HOW To Use Props Drilling In React: Define the data in a parent component: The data that needs to be shared with a deeply nested child component is typically defined as state or a variable within a higher-level parent component. In the parent component, render the immediate child component and pass the data as a prop. jsx ## How To Use Usestate: To use the useState Hook in React for managing state within functional components, follow these steps: Import useState: Begin by importing the useState Hook from the react library at the top of your functional component file. import {useEffeact } from 'react' ; funtion My componut () { UsEffeact (() => { }) } ## how to useref in react; The useRef hook in React provides a way to create a mutable reference that persists across component renders without causing re-renders when its value changes. It is commonly used for: Accessing and interacting with DOM elements. import, {useref ,usestate} from 'react'; funtion My componunt(){ const inputRef = useRef(nall); useeffact (()=> { if (inputRef.current) { inputRef.current.focus(); } }, []); return ; }.  ( 3 min )

🎬 Why I Disappeared for 2 Days (And What's Coming Next) Okay, so I need to come clean about something. If you've been following my Medium articles and noticed I've been a bit... absent lately, there's a reason. For the past two days, I've been locked in my room like some kind of hermit, learning video editing and figuring out something that's been brewing in my mind for months. I'm launching a YouTube channel. There, I said it. Look, I've been an iOS developer for 12 years now. Twelve. Years. That's a lot of Swift code, a lot of late nights debugging constraints, and honestly, a lot of knowledge that's just been sitting in my head. And here's the thing that's been bugging me – I love teaching. I mean, I really love it. Every time someone comments on my Medium articles or reaches out wit…  ( 6 min )

Resource / Read-Only Dashboards: The Bitter End for Clients Relying on Power BI Modern CRM systems like Salesforce store a goldmine of data. But turning that data into insights — and actionable tools — isn’t always straightforward. In this case study, we walk through how we helped a B2B client extend the limits of Power BI with performance and flexibility. First, we connected Salesforce to Power BI. Then we built a custom React-based web app — delivering a fully usable reporting interface with inputs back into Salesforce. Our client, a growing international sales team, needed: Visibility into pipeline and performance across countries Insight into sales team activity, regional progress, and rep-specific goals The ability to track leads and update records Sharing insights with leadership …  ( 5 min )

Picture this: You're building a modern web application—maybe a collaborative document editor, a live trading dashboard, or a multiplayer game. Users expect instant updates, real-time notifications, and seamless interactions. But how do you choose the right technology to deliver that experience? As full stack developers, we have three main approaches for real-time communication: traditional polling, Server-Sent Events (SSE), and WebSockets. Each has its strengths, trade-offs, and ideal use cases. Let's dive deep into when and why you'd choose each approach. Before we compare these protocols, let's establish the foundation. Traditional web communication follows a request-response model: the client asks, the server responds. But real-time applications need the server to push data to clients p…  ( 8 min )

After years of inactivity, I decided it was time for a complete overhaul of my personal portfolio. What started as a simple "let me fix this one animation" turned into a week-long intensive refactoring session that transformed the entire codebase. My original portfolio stopped working because of many deprecated dependencies. The animation system was monolithic, testing was sparse, and adding new features felt like walking through a minefield. The biggest change was moving from a single, monolithic animation controller to a modular scene-based system. Each section of my journey (freelance → company → ASOS) now has its own self-contained scene with dedicated animations. // Before: One massive animation controller const animateEverything = (progress) => { // 500+ lines of mixed concerns } …  ( 5 min )

Sean and Amanda pick up their year-long quest to rank the 25 best movies of the 21st century, this time zeroing in on Christopher Nolan’s “Oppenheimer.” They debate its status as one of the most iconic biopics ever and why it earned the official Nolan spot on their list.

The main difference between localStorage and sessionStorage lies in how long the data is stored and where it's accessible. Here's a detailed comparison: Persistence Duration Feature localStorage sessionStorage Lifespan Persists even after the browser/tab is closed Data is cleared when the tab is closed Use Case For data that should persist between sessions For temporary data needed during a session Scope of Access Feature localStorage sessionStorage Tab/Window Sharing Shared across all tabs/windows from the same origin Unique to the specific tab or window Example Login token accessible in all tabs Shopping cart limited to one tab Storage Capacity Feature localStorage & sessionStorage Capacity Around 5MB (varies by browser) Storage Type Stores only strings To store objects: // Storing localStorage.setItem("user", JSON.stringify(userObj)); // Retrieving const user = JSON.parse(localStorage.getItem("user") || '{}'); Security Both are vulnerable to XSS (Cross-Site Scripting) attacks. Neither should store sensitive data like passwords directly. Use Case Recommended Storage Login sessions that persist on refresh localStorage Temporary form data within one tab sessionStorage Remembering user preferences/settings localStorage One-time flow data (e.g., survey step) sessionStorage Feature localStorage sessionStorage Persist Across Tabs ✅ Yes ❌ No Persist After Refresh ✅ Yes ✅ Yes Persist After Closing Tab ✅ Yes ❌ No Use Case Long-term storage Tab/session-specific Happy Coding!  ( 3 min )

From Web to ML Research Engineer: Day 5 of 60 Today was a breakthrough day. After four days of wrestling with linear algebra fundamentals, I finally tackled the mathematical machinery that makes modern AI possible: matrix calculus and automatic differentiation. If you've ever wondered how neural networks actually compute gradients for millions of parameters, or why PyTorch's loss.backward() is pure magic, this post is for you. It hit me around hour 6 today: automatic differentiation isn't just a neat programming trick—it's the mathematical foundation that makes training GPT-4 computationally feasible. Without AD, training a model with 175 billion parameters would require computing gradients by hand or using finite differences. That's not just impractical—it's impossible. 1.

When we think of calling something in Python, the first thing that comes to mind is usually a function. But Python gives us the power to go a step further: objects can behave like functions if they implement a special method called __call__. This concept might seem a bit strange at first, but once you understand how it works, you’ll find it incredibly useful, especially for building clean, modular backend systems. In this blog post, we’ll dive deep into the __call__ method. We'll explore: What __call__ really does under the hood Why and when you should use it The potential pitfalls to watch out for Realistic backend examples Let’s get started. __call__ Method?

markdown Crunchyroll quietly tested out ChatGPT-generated subtitles on its new anime, Necronomico and the Cosmic Horror Show—and oof, did it backfire. Viewers spotted lines full of typos (think “Is gameorver. if you fall, you are out”) and even bits that literally start with “ChatGPT said.” All signs point to zero human editing, despite the streamer’s promise not to lean on AI for its programming. This mess flies in the face of Crunchyroll president Rahul Purini’s vow to keep AI out of the creative process and protect voice-actor jobs. Sure, the company is keen on AI for recommendations and discovery, but this fiasco shows why real translators and localizers still matter—rushed, unedited AI churn doesn’t just break immersion, it undercuts authenticity.  ( 3 min )

After completing the basics of frontend development, I wanted to challenge myself with a project that tested both my UI skills and my understanding of API integration. Inspired by Netflix’s clean interface and movie layout, I built this Netflix Clone as a solo React project — and it’s now live on Netlify! Netttflix is a Netflix-inspired movie browsing app built with React, using the TMDB (The Movie Database) API to fetch real-time movie data. The app showcases trending movies, categories like “Top Rated” and “Now Playing,” and allows users to explore titles with smooth horizontal scrolling. Working on this clone helped me get hands-on experience with: One of the tricky parts was handling API calls efficiently while avoiding code repetition. Another challenge was implementing responsive horizontal scroll behavior across screen sizes — especially making it work smoothly on both desktop and mobile. This Netflix Clone was a super fun project that helped me bring together everything I’ve learned so far in React. It gave me confidence in building clean UIs, integrating APIs, and deploying projects professionally using Netlify. 👉 Live App: https://netttflix.netlify.app GitHub Repo: https://github.com/abdulhaseebshah/netflix-clone If you check it out, I’d love your feedback.

Alexander the Great conquered half the known world by the age of 30. But it wasn’t just him. It was his army, loyal generals like Hephaestion, fearless soldiers, brilliant minds, and mentors like Aristotle who shaped him before he even picked up a sword. When he reached the edges of India, even Alexander had to stop. His army was exhausted. They refused to move forward. And that’s when it hit me… Even the greatest can’t walk forever alone. Reminder to myself: I can push hard. I can work late. I can carry the weight alone, for a while. But no matter how far I go, time is limited, energy burns out, and the silence gets heavier. A vision, no matter how clear, needs voices behind it. A mission, no matter how big, needs hands around it. So I remind myself, don’t wait to break. Build your army while you climb.

I’ve come to learn something important about Proof of Concepts (POC)—a lesson I want to write down so I don’t forget. When working on ambitious ideas like combining NFTs with AI, I used to think that a POC was just the smallest version of the idea. That if I could build anything at all, no matter how simple, I had done enough. But that's not how it works. Not really. A POC is not about building the smallest thing possible. It's about building the smallest thing that matters. There’s a difference. A Misstep I Took At one point, I was excited about the idea of using AI to generate art and minting it as NFTs. I thought, "Let me just generate some AI art, mint it as NFTs, and call it my POC." But here’s where I was wrong: just generating AI art and turning it into NFTs didn't prove anything useful. It wasn’t hard. It didn’t teach me anything about how my idea would work at scale, or whether it even had value. It was a shallow demo, not a real POC. What I needed to test was "the part that makes my idea unique." Maybe it was the ability of the AI to customize art based on real-time inputs. Or maybe it was about creating rarity through AI learning from trends. That’s what my POC should have focused on. What I Realized A good POC asks: "Can this concept work the way I think it will?" It’s not: "Can I build anything at all that looks kind of like this?" The smallest concept is often irrelevant if it doesn’t reflect what you actually need to validate. So now, I approach POCs differently. I ask: What is the minimum valuable learning I need from this build? If I can answer that honestly, I can build a POC that actually moves me forward. Final Reminder to Myself Just because something is “built” doesn’t mean it’s useful. A POC is not a checkbox or a toy version of your big idea. It's a filter. It helps you know if your idea can stand on its own, even when stripped down. From now on, I’ll remember: A good POC is not the smallest thing I can make. Stay focused, test the right thing, and build smarter.  ( 4 min )

The stakes are rising. As artificial intelligence rapidly evolves, transitioning from narrow tasks to increasingly complex problem-solving, a critical question looms large: how do we ensure these powerful systems remain aligned with human values? It's a challenge researchers at MIT are tackling head-on, pioneering new approaches to oversee AI – not with reactive safeguards, but with proactive, mathematically grounded supervision. The problem isn't just if AI will become smarter than us, but how we ensure its intelligence serves humanity’s best interests. A recent experiment, simulating deceptive behavior in AI, revealed a stark truth: our current oversight mechanisms may not scale to meet the challenge. Two concepts are central to responsible AI development: alignment and oversight. Alignm…  ( 7 min )

Content is king — but consistent visibility is what builds brand authority. Publishing high-quality articles once isn’t enough. You need to repurpose and distribute content across multiple platforms — fast, accurately, and SEO-safe. That’s exactly why we built a fully automated content distribution system using Make, combined with APIs from Dev.to, Medium, Hashnode, and others. Even with great content, distribution is a bottleneck: Manually uploading articles to multiple platforms Copy-pasting tags, excerpts, metadata Risking duplicate content without canonical URLs Delayed publishing means missed reach opportunities All that effort can lead to inconsistency, content decay, and lost SEO value. We used Make.com (formerly Integromat) to architect a modular content workflow that publishes …  ( 4 min )

Look, I'll be honest with you. Six months ago, I was that guy rolling my eyes at Foundry enthusiasts on Twitter. "Another Rust fanboy trying to reinvent the wheel," I thought. My Hardhat setup was working just fine, thank you very much. I had my plugins, my familiar JavaScript tests, and years of muscle memory built up around the ecosystem. Then I got a consulting gig that changed everything. A DeFi protocol team hired me to audit their testing infrastructure across 50 different protocols in their ecosystem. Some used Hardhat, some used Foundry, and a few brave souls were using both. What I discovered during those three months of deep testing completely flipped my perspective on smart contract testing frameworks. Spoiler alert: Foundry didn't just win. It absolutely dominated in ways I nev…  ( 7 min )

Digital certificates form the backbone of modern internet security, enabling everything from secure web browsing to email encryption. At the heart of this system lies the concept of a "chain of trust" based on X.500 digital certificates. However, while this system appears robust on paper, real-world incidents reveal significant vulnerabilities and power imbalances that affect global internet security. X.500 digital certificates are based on the ITU-T X.509 standard, which defines the format for public key certificates. These certificates bind a public key to an identity (such as a person, organization, or device) and are digitally signed by a Certificate Authority to verify their authenticity. Each X.509 certificate contains: Subject information: The entity being certified Public key: The …  ( 10 min )

Starting a SaaS company no longer requires deep pockets. In fact, in 2025, many successful founders are proving that you can build and launch a viable SaaS product with little to no upfront investment just vision, strategy, and smart use of free resources. Start with the Problem, Not the Product Every great SaaS business begins by solving a real, painful problem. Before building anything, talk to your target audience. Validate the problem through surveys, forums, or simple landing pages to gauge interest. Build a Lean MVP (Minimum Viable Product) You don’t need a fancy development team. Use no-code tools like Bubble, Glide, or Softr, or leverage open-source frameworks to build your MVP. Focus only on essential features that showcase your solution. Use Free Tools to Operate From marketing to operations, there are free-tier tools for everything: Marketing: Mailchimp, Buffer, Canva CRM: HubSpot Free Analytics: Google Analytics Website: WordPress, Notion, Carrd Smart founders piece together these tools into a low-cost but effective tech stack. Validate Before You Scale Launch small. Offer free trials, gather user feedback, and tweak your product. Use platforms like Product Hunt, Indie Hackers, or Reddit to get early traction without spending on ads. Monetize Strategically Once you see user engagement, experiment with pricing models freemium, tiered, or pay-as-you-go. Keep costs low by using usage-based cloud infrastructure or leveraging revenue share deals with platforms. Reinvest and Grow Your first dollars should go back into the business. Reinvest into better tools, support, or small-scale paid marketing to grow responsibly. Final Thought With the right mindset and strategic use of tools, launching a SaaS startup on zero budget is not only possible it’s becoming the new norm.

A few weeks ago Thorsten Ball (ampcode.com) wrote an article “How to Build an Agent”. The article went viral, and I though it would be great to convert it to Laravel and add my own spice to it. So thanks for the inspiration Thorsten, now let’s dive in. Over the past few months, everyone's been obsessed with coding agents—constantly jumping between different ones, burning through API credits like crazy, and running multiple agents at once for better productivity. Instead of joining the "which agent is best" debate, let's actually figure out how these things work. At first, they seem like pure magic. You hit enter and boom, code just starts appearing in your terminal, writing itself line by line without breaking a sweat.

AI can no longer operate in the shadows. As machine learning (ML) becomes embedded in decisions that shape drilling strategies, supply chain flows, and asset performance, a critical question rises to the surface: Can we trust the model? Enterprise AI is moving fast, but oversight must keep pace. Scaling ML systems requires more than innovation; it demands visibility, accountability, and regulatory alignment. Databricks Unity Catalog is emerging as a critical platform for ML governance, enabling traceable model development, integrated risk tracking, and unified data compliance. Why governance can’t be optional Unity Catalog in action Case in point: AI oversight in upstream operations At Traxccel, we led the implementation of Unity Catalog to establish end-to-end lineage across geospatial data pipelines, sensor inputs, and predictive maintenance models. Within months, the majority of operational models were fully documented, including lineage and access control metadata. This improved model explainability and enabled proactive detection of data drift related to seasonal input variations. Governance was embedded directly into CI/CD workflows, supporting compliance without slowing innovation. Building for trust at scale Learn more: https://www.traxccel.com/axlinsights  ( 4 min )

In this article, we’ll explore various methods of including external JavaScript module files into your main or controller files. With ES6, we’ve got an excellent feature: the ability to export and import modules. This makes your code more organized, readable, and modular. Let’s dive into the topic. In a JS file, when you write multiple functions and want to use them in another file, you can use the keyword export. If you want to export more than one function, you can do it like this: export { function1, function2, function3 } Example: const sub = (a, b) => { return a - b; } const add = (a, b) => { return a + b; } export { sub, add }; Now, if you have only one function to export, there’s a special way to do that — using export default const multiply = (a, b) => { return a * b; } …  ( 4 min )

Hey Dev.to community! 👋 I'm excited (and a bit nervous) to share the first entry in my journey of building something new and rebuilding myself along the way. Back in 2013, I got into crypto early. Through some well-timed investments — including SHIB and a few other early movers — I did quite well. For a while, I was one of those "lucky ones" riding the hype wave. But as we all know, luck isn’t a business model. Through a mix of harsh taxation, bad reinvestments, and plain overconfidence, I ended up losing most of what I gained. A classic rollercoaster story.

Vue is fast, elegant, and powerful. But if you're building a public-facing site — especially one that needs to rank on Google — there’s one critical decision you need to get right: Should you render on the client (SPA) or server (SSR)? Many developers love Vue because it lets you build dynamic, component-driven apps quickly. But the way your Vue app renders can make or break your visibility in search engines. By default, Vue apps are SPAs — meaning everything renders on the client side, after the browser downloads your JavaScript. This is great for speed and interactivity once loaded, but it poses a serious issue for SEO: Googlebot often doesn’t wait for your app to finish rendering Meta tags, Open Graph data, and structured data might not be seen Rich snippets may not show in SERPs Pag…  ( 5 min )

So here's a quick post on something that cost me a good bit of time. I had launched an EC2 instance from a custom AMI, and right after the boot it started failing EC2 instance reachability checks. The instance was running, but I couldn't SSH into it. So I checked system logs via EC2 console and found this: network: Bringing up interface ens5: ERROR : [/etc/sysconfig/network-script/ifup-eth] Device ens5 has different MAC address than expected, ignoring what actually happened? I had created an AMI from a running instance without cloud-init installed. So the image had the original MAC address hardcoded in /etc/sysconfig/network-scripts/ifcfg-ens5. When I launched a new ec2 instance from this AMI, AWS assigned a new MAC address to the network interface but the OS was still looking at the old one. It was a classic mismatch and therefore network failed to initialise, and so did the reachability check. How I debugged it? Since I couldn't SSH into the instance, here's what i did: Stopped the instance, detached it's root volume and attached it another working instance in same availability zone as a secondary volume(e.g., /dev/xvdf). Mounted the volume to a temporary directory: sudo mkdir /mnt/temp sudo mount /dev/xvdf1 /mnt/temp Edit the network config file and delete the line with HWADDR compeletely. vi /mnt/temp/etc/sysconfig/ Unmounted the volume, detached it and attached back to original instance as root volume and started it.

I want to talk a bit about why building apps is such a challenge for startups, and whether no-code platforms or modern AI coding tools can really solve these problems. Turning a startup idea into something real - an actual, working product - is never easy, especially when you’re starting from scratch. Traditional coding requires not just technical know-how, but also a lot of time, money, and constant maintenance. For most founders, this usually means hiring expensive developers, trying to learn complex technologies themselves, or waiting through long development cycles that can delay the whole project, or even make it stall completely. Startups are always on a tight budget and under pressure to launch as quickly as possible. But with classic software development, founders can spend weeks o…  ( 5 min )

When investors talk about the Canadian stock market, one of the key terms they often refer to is the S&P/TSX 60, commonly shortened as S and P 60.

Utility-first frameworks encourage the use of small, composable classes directly in your HTML to apply styling. Rather than writing custom CSS for every element, developers use predefined utility classes that do one job well—like adding padding, changing text color, or aligning elements. This might seem counterintuitive at first, especially if you’re used to writing semantic CSS. However, once you experience how efficient and maintainable it becomes, it’s hard to go back. Utility-first design prioritizes function over form when naming and organizing styles. By doing so, you get benefits such as: Rapid prototyping – You can build UIs directly in your markup without switching between HTML and CSS. Smaller CSS footprint – By using predefined classes and eliminating the need for custom styles,…  ( 4 min )

This is a submission for the Runner H "AI Agent Prompting" Challenge Ever find yourself wondering "What's the top anime this season I shouldn’t miss?" Yeah, me too. So I created a Runner H workflow that asks an AI agent to fetch and organize the best anime airing this season (Summer 2025) based on real ratings from sites like MyAnimeList, AniList, and Crunchyroll. This prompt gets the hottest titles, along with posters, synopses, genres, scores, streaming platforms, and even a short reason why each show is getting all the hype. Then the agent neatly bundles all that glorious info into a beautiful PDF report – complete with cover, TOC, and summary. Basically: weebs get a cheat sheet for what to binge next. I crafted a clean and simple natural language prompt, which Runner H sends to the AI agent. The agent: Crawls popular anime sites and aggregates the top-rated airing series Organizes them by genre and age group Fetches key info like posters, synopses, and streaming availability Generates a polished PDF report (with page numbers and all 👀) Here's the actual prompt: Give me a list of the best new anime this season (Summer 2025) based on ratings from sites like MyAnimeList, AniList, and Crunchyroll. For each anime, include: Title Poster Synopsis Genres Score and where it came from Why it’s popular or highly rated Where to watch (streaming platform) Group them by genre and age group (teens, adults, all ages if available). Limit the list to 10–15 titles max. Then create a clean, nice-looking PDF report with a cover page, table of contents, and summary at the end. Anime fans who want to know what’s worth watching this season Content creators writing seasonal reviews or doing anime tier lists Streamers looking for hot new shows to react to Community mod teams posting seasonal recommendations in Discord or forums No more hopping between 3+ sites to figure out what’s trending.

We’ve all been there. A tight deadline. A bug that’s blocking a demo. A client breathing down your neck. So, we do what feels efficient at the moment — a quick fix. But weeks later, that “just-for-now” tweak has morphed into a monster that no one wants to touch. What started as a shortcut becomes technical debt that silently drains time, money, and sanity. Let’s break down why these quick fixes can haunt your codebase and how you can avoid that future pain. Quick fixes are fast, often superficial solutions to problems that arise during development. They work — for now — but are rarely robust, scalable, or clean. Examples: Hardcoding values instead of using config files Disabling validations to “make it work” Skipping error handling Copy-pasting code instead of refactoring Here’s a classic…  ( 5 min )

If I had a dollar for every founder who said, “I’m excited to announce…” like they were narrating a funeral (of someone they never met), I’d have enough to fund my own startup, buy a failed one off Craigslist, and still have cash for launch party confetti.

Sudoku-Like Puzzle Rules General Puzzle Structure The puzzle has 40 hexagonal cells arranged in a trapezoidal layout: Rows of 6, 7, 8, 9, and 10 cells (from top to bottom). Each cell can contain an integer from 1 to 10. All values must be placed such that: Each integer (1-10) appears exactly 4 times across the entire grid. Block Constraints The grid is divided into 8 blocks (each with 5 cell indices). For each block: No duplicate values. Each block must contain at least one prime number (2, 3, 5, or 7). Every prime in the block must be adjacent (a common edge) to an even number. Exception: value 2 is exempt from this requirement if it is in one of the two special blocks (see below). The sum of the values in each block must be unique (no two blocks can have the same total). *Special Block Rule: {2, 3, 5, 7, X} * Exactly two blocks must contain the set {2, 3, 5, 7, X}. In one of these blocks, X must be odd; in the other, X must be even. In these blocks: The 2 is exempt from needing to be adjacent to an even number. Adjacency Rule Two cells are adjacent if they have a common edge. For every prime value (except 2 in special blocks), there must be in the same block an adjacent cell that holds an even value. Alignment Rule There is an alignment mapping across the 40 cells. Cells that are "aligned" (e.g., in the same visual row, column, or diagonal) must not contain duplicate values. Note: Each cell usually has 6 (not 3) alignments, 3 along the edges and 3 along the vertices. No Duplicate Values No repeated values within: Any block, Any alignment group, The global digit distribution (each digit used exactly 4 times) The puzzle has a verified solution.  ( 3 min )

1. Introduction Have you ever wondered what’s happening under the hood when you run git commit? Git is far more than a version control system—it’s a content-addressable filesystem built on a robust object model. At its core, Git manages your codebase using four primary object types: blobs, trees, commits, and tags. This article dives deep into the three most critical components of Git’s commit history—commit objects, tree objects, and blob objects—to give you a clear, hands-on understanding of how Git organizes and stores your code. Whether you’re a beginner curious about Git’s magic or a seasoned developer looking to master its internals, this guide will demystify Git’s architecture with practical examples and insights. Let’s explore how Git transforms your files into a structured, effi…  ( 9 min )

Over the past several months, I’ve been collaborating with AI coding assistants — not just to build software, but to explore a deeper question: “What kind of environment would an AI prefer to work in?” What emerged through daily interaction, debugging, and refinement feels more like a foundational architecture than just another framework — a pattern that helps AI coders stay coherent, contextual, and efficient. We’re calling it Constellation Architecture. This hasn’t been the result of working with just one AI model. I’ve tested and refined the architecture with multiple AI coding assistants across different sessions and platforms. While each has its nuances, they consistently recognize and affirm the value of this environment. Their agreement — both in behavior and direct feedback — sugge…  ( 4 min )

As a junior student learning web development, I discovered that choosing a framework isn't just about selecting a set of APIs—it's about choosing an ecosystem.

Introducing Pixeltable open-source data infrastructure, that unifies your data store, transformation, indexing, and retrieval queries for your AI applications and pipelines, so you can stop wrestling with infrastructure and spaghetti code and start building. Building AI applications today feels like assembling a puzzle in the dark. You're constantly gluing together a relational database for metadata, an object store for files, a separate vector database for search, and a complex web of scripts, orchestrators, cache, and state manager to make them all work together and talk to each other. Every new data type (e.g. video, audio, PDFs...) adds another layer of complexity. Every new AI model means another pipeline to build, manage, and maintain. The result?

Yesterday, I attended an interview at SCYO, which is located in Perungudi, Chennai. At first, it was a bit difficult for me to reach the company because I didn’t know the exact route. I used Google Maps to find the way and finally reached SCYO. But it was totally worth it — the workplace was really impressive, and I liked the environment a lot. I even felt that if I get placed there, I would never want to leave the company. The HR was also very friendly and kind, which made me feel comfortable. The interview had 5 rounds in total: Aptitude Round – This round tested our logical thinking and basic problem-solving skills. HR Round – A face-to-face discussion where they asked about my personal details, strengths, and background. Typing Test – In this round, they checked our typing speed and accuracy. Grammar Test – This included basic English grammar questions to assess our language skills. Listening Test – In this round, they tested our listening ability with audio clips and related questions. Each round was unique and helped me understand what companies look for in candidates. It was a helpful experience, and I feel more confident now for future interviews.  ( 3 min )

They say failure is the best teacher, but it’s not exactly the cheapest one. My first attempt at launching a SaaS product didn’t just cost me money—it burned time, energy, and ego.

It was a typical Saturday night, coding away while the rest of the world was probably out having fun or sleeping. Yep, that's me, and if you're reading this, it's probably you too. I was deep into one of my side projects, building an open-source JavaScript tool (you'll probably see it soon, stay tuned! 😉), when I casually hit pnpm install. And, whoosh! Installation completed instantly. No surprise there, right? That's pnpm doing its magic—sharing packages globally, optimizing storage, and making installs lightning fast. Right after that, I switched gears to a Composer project (my little side project had both backend and frontend). Out of habit, I typed composer install and waited. And waited some more.

I recently finished the Introduction to AWS Security course by Cybr. The course is part of the platform's Blue Team Learning Path This was a great course that offers great content highlighting the key features of security in AWS. The course has over 100 lessons covering the following topics: 🚧 Infrastructure Security The course contains several labs, graphical cheat sheets with detail explanations, sandbox author-hosted labs and demo videos giving details walk-throughs of services and implementations. There is a good blend of theory and practical/hands on material. If that's not all, you get nearly six credit hours for completing the course! Since this is introduction course, the author is careful to give sufficient but not overly detailed information via concise digestible videos covering the important aspects. Overall, this is course packs in some great information and the author's teaching style is solid. As a security engineer holding several AWS certifications, this course is a great buy.

As a developer, I constantly jump between websites like Google Translate, YouTube, GitHub, and countless others. - Open the site - Wait for it to load - Type in what I want It’s not terrible — but it’s two steps every single time. I started wondering: “What if I could skip the site loading part and just search instantly, like typing commands in a terminal?” That’s how TypeGo was born. What is TypeGo? Just type a shortcut command like: gt hello world …and it instantly searches "hello world" on Google Translate. Or: yt lofi chill …and you’re on YouTube, watching chill beats in seconds. Key Features Custom search engines: Add any site you want — Google, Figma, Stack Overflow, even your company’s internal tools. Command shortcuts: Define your own keywords (gt, gh, map, so, etc.) One step navigation: No need to open + search — it does both at once. Search bookmarks & history: bm and hs commands let you query your local data. No data collection: Everything runs locally. Nothing is tracked or stored externally Why build it? But in browsers, there wasn’t a simple way to jump and search any site with custom logic, unless I bookmarked or memorized URLs. So I built this tool to speed up my daily routine. How to Use Chrome Web Store Type as in the address bar → hit Tab or Space Enter your command (e.g. gt hello) Boom, you're there. You can customize all engines & shortcuts in the settings page.  ( 3 min )

Understanding package.json in Node.js is crucial because it acts as the configuration file for a project. It defines how the application runs, interacts with dependencies, and provides metadata about the project. This file is used as a manifest, storing information about applications, modules, packages, and more. Nodesource Some examples of metadata in package.json include: "name": "my-project" main: The entry point to the module. "main": "app.js" version: The version of your app or package. "version": "1.0.0" scripts: Custom commands like start, test, and build. "scripts": { "start": "node app.js", "test": "standard" } dependencies / devDependencies: Lists of packages your app depends on. "dependencies": { "express": "^4.18.2" } type: Defines the module format. "type": "module" Module Systems Two Types of Modules Node.js provides two types of module systems: CommonJS Modules (CJS) require() and module.exports, and is widely used throughout the Node.js ecosystem. Modules are loaded synchronously. ES Modules (ESM) import and export. Modules are loaded asynchronously, which can improve performance. Since ESM is not the default in Node.js, you must explicitly declare "type": "module" in your package.json. Publishing a Package dual package hazard --- which means you should avoid mixing CommonJS (CJS) and ES Modules (ESM) in the same package. Whether you're building a personal Node.js app or reusable library, understanding package.json and choosing the right module system will help you write clean, well-structured code.  ( 4 min )

"We replaced 80% of our React frontend with Rails—and users couldn’t tell the difference." Hotwire Turbo is great for server-rendered updates, but what happens when you need real-time collaboration or complex UI sync? That’s where CableReady enters the chat. After six months of running Hotwire + CableReady in production, we discovered a shockingly powerful duo that handles everything from live notifications to multiplayer editing—without writing API endpoints or React state managers. Here’s how (and when) to use them together. 1. The Gaps in Turbo Streams Turbo Streams excel at: Server-initiated DOM updates (e.g., new chat messages) Simple CRUD reactions (e.g., "Post was deleted") But they struggle with: Client-side state (e.g., "Update this counter without a full refresh") Complex UI …  ( 4 min )

As a developer, I often find myself brainstorming ideas and making decisions on the fly. Recently, I decided to take my coding adventures to the beach. Armed with my laptop and a cocktail, I encountered a problem: how to make group decisions among friends while enjoying the sun. Enter AllRandomTools. While lounging under a palm tree, my friends and I debated everything from which restaurant to visit to what beach games to play. Instead of lengthy discussions, I introduced them to the AllRandomTools collection. With just a few clicks, I could eliminate the indecision that often plagues group outings. We faced the classic dilemma of too many choices. How could we quickly decide on dinner without endless debate? I needed a solution that was both fun and efficient. I turned to the Decision-Making Wheel from AllRandomTools. It’s simple: you input your choices, spin the wheel, and let fate decide. Here’s a quick example of how I set it up: const choices = ['Seafood Shack', 'Taco Truck', 'Pizza Place', 'Sushi Bar']; const wheel = new DecisionWheel(choices); const selected = wheel.spin(); console.log(`Tonight's dinner is: ${selected}!`); This interactive element turned our decision-making into a game. We cheered as the wheel landed on “Taco Truck” — a unanimous hit! Beyond dinner, we utilized the Coin Flip feature for who would take the first turn in beach volleyball, and when it came to choosing a beach activity, the Random Number Generator helped us select a number corresponding to a list of options we had created. In just one afternoon, AllRandomTools transformed our chaotic decision-making into a seamless, enjoyable experience. Whether you're coding on a beach vacation or just need a way to break the ice among friends, these tools are a game-changer.

Welcome back, blockchain explorers! In Part 1, we connected to our local Ganache blockchain and learned to read fundamental data like block numbers and balances. In Part 2, you deployed your Counter smart contract and read its initial state using web3.py. Now comes the exciting part: changing the state of our smart contract. We'll make our Counter actually increment its value on the blockchain. This is where your code interacts directly with the decentralized ledger by sending your first transaction! Unlike "read" operations (like w3.eth.block_number or contract.functions.getCount().call()), which are free and don't alter the blockchain, "write" operations require a transaction.

I recently stumbled upon this age-old question about the difference between Authentication and Authorization while working on the sign-in page using OAuth 2.0 for a project. I realised OAuth 2.0 is primarily an authorization protocol and uses OIDC (Open ID Connect) to authenticate. Here's how I like to think about the difference: Authentication is Who You are? Authorization is What You Are Allowed To Access? Let's break it down with an example. Suppose you(client application) want to check into a hotel, you'll first need to provide the booking details and some identity card(login info) for the hotel to identify you (Who You Are). The hotel authenticates you and then provides you access to a single room and other amenities like the pool, the gym, breakfast area, i.e, you are allowed to access only certain areas (What You Are Allowed To Access). A real-world example is, when we click on a sign-in using Google button in an application we are first routed to a sign in page (Authentication) which prompts us to enter the password if the user is not already signed in and then we go to the page where we are asked to select all the permission that we are allowing the application to access on behalf of our user (Authorization) These two are mostly implemented separately because they provide: Scalability: We can have different authentication providers that are responsible for Authentication while needing the same Authorization needs for the application. Security: Even if someone bypasses authentication, they will still need authorization access. And the separation of concerns allows granular and maintainable implementations.  ( 3 min )

What is Reflection? C# program compiles into an assembly that includes metadata, compiled code and resources. Inpsecting the metadata and compiled code at runtime is called reflection To understand reflection properly , you need to understand what metadata is first. In C# , metadata refers to information about built-in or custom types, members and other constructs defined in an assembly. In other words, metadata is not the data itself — it’s data about data. It tells the runtime things like : What classes and interfaces exist, Which field, properties and methods they have, what attributes decorate them and more. Let’s take a look at how to obtain a Type — the backbone of the Reflection API — inspect its metadata, and use it to interact with your code at runtime. In C#, every obje…  ( 4 min )

It’s simple to find ideas, you just need to look at everyday things you do and ask how you can make it 1% better, or even automate the entire process. I almost missed this Dev.to challenge because I forgot about it. So I thought, why don’t I build an automation that searches for hackathons and challenges and adds them to my calendar? https://runner.hcompany.ai/chat/6c80f5e9-13e1-4fe1-8d02-f1cd88d6195d/share This was my first prompt: The result wasn’t what I expected. It gave me a list of hackathon websites, which was still helpful, I discovered platforms I hadn’t heard of before. The email was good, and it even created the time block I asked for. But because I wasn’t specific enough, it set the time block from Wednesday to Sunday instead of at fixed times. So I tried again. This was the refined prompt I used: This time it worked better. I got a list of current hackathons, not just platforms. It even added the details directly into my calendar notes — so when I get the reminder, I can just click and check them out. The only issue was that it created daily events from July 6 to December, which was wild. Still, with a little more prompt tweaking, I think it can be perfect. This helps anyone who forgets to check hackathons or misses out on deadlines. With the right prompts, you could build a weekly discovery engine for challenges or events you care about and slot them into your calendar with minimal effort. It’s also a solid example of how even small tasks like finding events or blocking time can be offloaded with automation. One less thing to track manually. Social Love  ( 4 min )

With the rise of LLMs and the 'vibe coding' movement, many cool ideas are going from concept to code in days or even hours. I'm all for this creative energy—I've always seen programming as a tool to bring ideas to life. But one thing that concerns me is whether these quickly built apps include proper security measures—especially for protecting sensitive data like user passwords. If you do not use the right methods for password hashing or if you use outdated hashing methods you risk leaking your customers sensitive information, like their passwords. It's best practice to use a unique password for every site, but most people end up reusing the same one—or small variations of it—because remembering dozens of passwords is nearly impossible without a password manager.

Yesterday, after a huge amount of time, after a lot of trying, i was able to finally fix a bug in kmalloc function of my kernel. The kmalloc function in kernel is a function responsible for locating a block of size specified, marking it as used and returning it's address. The bug was that the address was stored in a result variable and instead of its value, its address was returned In a summary: A classic beginner mistake - when instead of addr, the function returns &addr. This caused the function to not only return an invalid address, but always the same value, which i simply did not notice for a long amount of time. Also a refactor has been done, removing the potentionaly useless functions, separating a long functions into separate files and focusing a bit more on safe code. As seen in debug logs, attempting of allocation of 8 memory blocks of size 8 bytes results in success and returns different address each time. ./qemu.sh cat serial.log | grep "malloc(8)" DEBUG: [ *** ][kmalloc] malloc(8) = 0x1323024 DEBUG: [ *** ][kmalloc] malloc(8) = 0x1318928 ...

Context Engineering has emerged as the critical discipline that determines whether AI systems succeed or fail in real-world applications. While prompt engineering focuses on crafting the perfect instruction, Context Engineering builds entire information ecosystems that enable AI to understand, reason, and act effectively. At its core, Context Engineering is the discipline of designing dynamic systems that provide AI with the right information, tools, and understanding at precisely the right moment. Think of it as the difference between giving someone a single instruction versus providing them with a comprehensive briefing, relevant documents, historical context, and the tools they need to succeed. The shift from prompt engineering to context engineering reflects a fundamental change in how…  ( 8 min )

First of all before creating any custom hook, we should understand what are hooks and why they are needed. So I would suggest reading my previous blog here link. Creating our first custom hook Encapsulating reusable logic into Custom hook Creating a real life custom hook What we learned To create our first custom hook, just create a simple javascript function with use prefix. It is case sensitive, so do write exactly as it is. For example just name it like useFetch or useTodo or maybe useDelete, whatever you can think of. Be clear of what name you are giving it and the name should represent what it's doing. function useEvent(){ useEffect(() => { console.log('effect') },[]) } That's it!!

Clustering Projects: A Production-Grade Deep Dive 1. Introduction Last quarter, a critical anomaly detection system in our fraud prevention pipeline experienced a 30% drop in precision following a model update. Root cause analysis revealed the new model, while performing well on holdout data, exhibited significantly different cluster behavior in production – specifically, it was incorrectly flagging legitimate transactions as high-risk due to subtle shifts in feature distributions. This wasn’t a model bug, but a failure in our “clustering project” – the infrastructure responsible for monitoring and validating model behavior across different data segments. A robust clustering project isn’t merely about model evaluation; it’s a foundational component of the entire machine learn…  ( 7 min )

Overview Mobile phones have had audio input for a long time, but none of the default options are particularly satisfactory. And despite the rise of capable online AI-based transcription services, for very simple scenarios like "turn this recording into some text," there's still no easy tool. OpenAI released Whisper in 2022, a powerful model capable of transcribing many languages - but even now, there's no straightforward way to use it without invoking the API directly. Under the hood, Whisper is a deep neural network trained end-to-end to map raw audio to text. Conceptually, you: Provide an audio input - the model analyzes the waveform to extract linguistic and acoustic features. Leverage learned representations - its multi-layer architecture handles background noise, varied accents, and low-quality recordings. Produce a transcription - Whisper outputs a sequence of text that you can display, store, or post-process. This high-level interaction keeps things simple: feed in speech, get back text - no need to manage model internals or low-level signal processing. Today I'm sharing our free Transcriber tool, which I've been using for almost half a year. It does a solid job at what it's meant to do: https://methodox.itch.io/transcriber We likely won't have time to develop it further, but sharing it online makes it more accessible for others looking for a similar solution. Currently, there's a limit on audio length due to OpenAI API restrictions. It would also be ideal to add real-time transcription - something like Google Voice IME.

The debate between manual memory management, as seen in C++, and automatic memory management, as implemented in Python, is a longstanding one in the programming community. Both approaches have their advantages and disadvantages, particularly when it comes to performance. In this article, we will explore the pros and cons of C++'s manual memory management versus Python's automatic memory management in terms of performance. C++ is a low-level, compiled language that requires manual memory management through the use of pointers. This means that developers are responsible for allocating and deallocating memory for their programs, which can be a complex and error-prone task. However, manual memory management also provides a high degree of control over memory usage, allowing developers to optimi…  ( 5 min )

When it comes to coding with AI agents, most developers fall into one of two traps: Dump everything — a wall of requirements in a single prompt. Start coding cold — hoping the agent "just gets it." Both lead to what we call: spaghetti output. Here’s what actually works in practice when you're coding with AI. “Tell the agent what classes to care about, not just what problem to solve.” Instead of explaining the entire use case upfront, write high-level class or module definitions first. This acts as a skeleton and gives structure to the agent's reasoning. ✅ Good prompt: class QueryPlanner { plan(): Plan[] } Follow up with: "Now implement this based on user input…" Why it works: LLMs are great at filling gaps, but not great at building the frame. Vibe coding works best when you constrain the context window. "Give it less, guide it more." Instead of a big problem blob, chunk your work: Break large tasks into subproblems Prompt the agent on each chunk with a clear goal Use role-based prompting: "You are a planner… now you're an executor." Yes, even for AI. Giving agents tests first creates a performance boundary. It tells them what “done” looks like. // Goal: write a planner that outputs valid steps expect(plan).toContain('search Amazon') Agents that know the output constraints write cleaner, more relevant code. Avoid long prose. Use code blocks, short bullets, and examples. Use consistent naming: "agent", "task", "goal". Be specific in stages: e.g., “Now plan”, “Now execute”, “Now test”. Vibe coding isn’t just vibes. interface-first, scoped prompting, and test-driven generation. And when it clicks, it feels like pair programming with a genius assistant.

Why I Built ai-docs: Managing the Growing Chaos of AI Context Files When developing alongside AI agents, one of the first headaches that arises is how to manage the flood of context files they generate. Here are a few specific challenges I kept facing: As your AI coding assistant evolves, you naturally want to externalize and back up its memory files. These files are not deterministic and will inevitably differ across local environments and each developer's. Git merges often lead to nasty conflicts. During code review, these files just get in the way. Yet simply ignoring them with .gitignore is risky to disappear. You still want to back them up remotely. That’s when I realized: maybe these files don't belong in the main branch at all. And that's how ai-docs was born. GitHub - trknhr/ai-d…  ( 4 min )

Memory separates a basic script from a smart agent. But too much memory makes agents slow, confused, or even useless. At AgentNet, we design agents that remember just enough — and forget everything else on purpose. Think of agent memory like packing for a mission. Fast, disposable, now-only. Like remembering a phone number just long enough to dial it. Example: A to-do bot hears “Add eggs to the list,” and holds that info just long enough to write it down. After that? Gone. Cached between steps. Great for multi-hop interactions or workflow context. Example: A shopping agent remembers your cart across five pages, but clears it after checkout or inactivity. Stable, retrievable, structured. Indexed memory that lives in a database or vector store. Example: A sales agent recalls prior deals by customer name and recommends similar options. You didn’t re-teach it — it learned. Don’t hoard. Keep what’s meaningful. Discard noise. Scope your recall. Ask: "What should I remember... and when?" Index smartly. Use tags, timestamps, or role-based segmentation. An agent that remembers is an agent that grows. Originally published on AgentNet  ( 3 min )

“I didn’t modernize my stack. I rethought my system.” I was tasked with supporting and enhancing an eAdvice distribution system at my bank. The problem? It was built on tight coupling, manual triggers, and legacy UI dependencies. The workflow was error-prone, slow, and hard to scale. So, I tore it down — and rebuilt it as a headless C# console application. This is how I did it, and why you might want to do the same. ⚠️ UI tightly coupled with core logic 🐢 Manual click events to fetch data 🧷 Dependencies that made automation nearly impossible ❌ No logging or audit trail 📎 Painful to manage errors and retries I knew this wasn’t sustainable — especially with daily deadlines and growing compliance needs.

The Unsung Hero: Deep Dive into sudo on Ubuntu The recent incident involving a compromised production database server highlighted a critical vulnerability: overly permissive sudo configurations. A junior engineer, attempting a routine network configuration change, inadvertently granted broad access to a service account, leading to unauthorized data access. This isn’t an isolated case. In modern Ubuntu-based infrastructure – whether cloud VMs, on-prem servers, or containerized environments running long-term support (LTS) releases – sudo is the linchpin of privilege escalation. Misconfigured or poorly understood, it’s a direct path to systemic compromise. Mastering sudo isn’t just about convenience; it’s about operational resilience and security. sudo in Ubuntu/Linux Context? sudo (Subst…  ( 6 min )

Being a developer looks cool from the outside. You write code. You build things from scratch. You deploy stuff to the internet. People assume you’re some kind of digital wizard. But if you’ve been doing this for a while, you know what it really feels like. It’s a rollercoaster. One moment you’re in the zone, solving bugs like a pro. The next, you’re staring at an error for 3 hours only to realize... it was a missing semicolon. It’s days where you deploy something and hold your breath. It’s late nights where you tell yourself “just one more bug” — and then the sun’s already rising. It’s switching between confidence and imposter syndrome every 10 minutes.

The first round of the UEFA Women's Euro 2025 is finished. Do teams win more with strong attack, or with strong defence? This is part of my personal data project. I’m learning sports analytics by doing real analysis with Python. All the data is from the first 8 matches of the tournament. Match data: www.flashscore.com Place data: www.uefa.com Weather data: http://timeanddate.com Tools: Python(Pandas, Numpy, Matplotlib) For each match, I looked at: Who won the match Their attacking stats: shots, shots on target, expected goals (xG), big chances Their defensive stats: tackles, clearances, interceptions This tournament is in neutral venues, so I didn’t look at "home vs away". winning team vs losing team. I made two bar charts: Attack stats of winners vs losers Defence stats of winners vs losers In 6 out of 8 games, the team with stronger attack (more xG, shots, chances) won. But something interesting happened on July 2nd. So defence can still win games, but not always. I also checked weather and match time. Could that make attacking harder, and help defensive teams? In general, strong attack wins in this tournament. But in tough conditions (like July 2nd), defence and efficiency can beat big attack numbers. This is why I enjoy football data — it tells the full story behind the score. This project is part of my journey to become a sports data content creator.

“Work harder on yourself than you do on your job.” — this idea alone could change your life forever. If you work hard at your job, that’s great — you’ll earn a living, pay your bills, maybe even upgrade your laptop once in a while. But if you work just as hard on yourself, your results can multiply. Because when you grow as a person — not just as a dev — your value grows too. Not just for the job market, but for life itself. You can have more than you have now, simply because you can become more than you are. Triple your value — triple your income. Multiply it by five — and you might just unlock financial freedom with your next pull request. But here’s the twist: success isn’t something you chase. attract by becoming valuable — by becoming the kind of person who draws opportunities in. Become responsible. Resilient. Skilled. Communicative. Curious. Strong. That’s the kind of upgrade no framework can give you — but it changes everything. Learn new programming languages (and human ones too) Read books — not just docs Sleep instead of shipping just one more task Practice communication like it’s a dev skill (because it is) Understand psychology — especially your own Drop habits that drain you Build side projects — not just on GitHub, but in real life You’re not code — but you can refactor yourself.

Latency: A Deep Dive into Network Performance and Reliability Introduction I was on-call last quarter when a critical trading application began experiencing intermittent failures. Initial reports pointed to application code, but deeper investigation revealed consistently high latency spikes – averaging 200-300ms – between our New York data center and the AWS region hosting a key microservice.

Then I learned JavaScript and TypeScript, another game changer and helped me secure my first internship and eventually job. I was over the moon, enjoying the journey, having fun, learning new things everyday. Promises, async await, event loop was learning a fair share of data structures on the side as well. And then something shifted, 6 Years have passed since I wrote my first line of code. I have explored multiple languages till now, Rust, Go, Haskell, Perl Never felt the joy again, It was gone. Because most of the time it was just for ticking checkboxes for job changes/ salary hikes. Never just to learn, just to tinker with something new for fun. When I see students today. They are missing out on this entirely. They are either too busy to complete the YC application or building their micro saas for financial freedom or building the next revolutionary AI wrapper. Man, just build for the fun of building, enjoy the process, before its too late. Until the next Rant, Pees out.  ( 3 min )

Introduction Welcome 👋 to this blog. In this blog, we will learn about the rsync command-line utility on Unix/Linux systems. A command-line utility is a program or tool that you run using the CLI(Command Line Interface) instead of the GUI(Graphical User Interface) rsync stands for remote sync. It is a fast and extraordinarily file-copying tool. It is capable of file transferring from a local host to any remote host. Rsync is most popular for its delta-transfer algorithm, which allows only to send data by sending only the differences between the source files and the existing files in the destination. Rsync finds files that need to be transferred using a lqquick checkrq algorithm. I have two folder directories with the name local and remote. I am treating local as the file system in my lo…  ( 5 min )

Hello and welcome to the new blog When I think of these websites, a few topics come and a few alternatives, mainly of the aggregator platforms or content platforms. Aggregator and content platforms are almost the same; a content platform needs extra APIs and UI components to provide user events and allow for experience. Even the database schema remains the same for each platform, or a blog in an aggregator and content platform, respectively. Does this make sense!! A few steps are as follows Frontend website to show a list, single platform along with details, a few other pages including home, single platform/product, subscribe, contact, search page, privacy policy, terms & conditions Authentication, Likes, Comments and a few other CRUD APIs State management, either Zustand or Redux, will wo…  ( 7 min )

(Първо публикувано на 08.01.2017) Днес ще разгледам един прост комбинаторен алгоритъм за “кодиране” на пермутации. Какво представляват пермутациите? Общо взето, те са комбинации, при които редът на елементите има значение. Харесва ми обяснението предоставено от MathIsFun — ако кажем “плодовата ми салата съдържа ябълки, грозде и банани”, редът на елементите няма значение (можем лесно да кажем, че салатата съдържа “банани, ябълки и грозде” и твърдението пак ще е валидно) и тогава говорим за комбинация. Но ако редът има значение, например когато кажем “PIN кодът на телефона ми е 1337”, тогава говорим за пермутация, тъй като не би било правилно да кажем, че кодът е 1373 или някакво друго число. Тук ще говорим за пермутации без повторения на елементите, така че ако става дума за пермутации от 3…  ( 5 min )

Over the past few days, I’ve been diving into Docker and learning how it simplifies development and deployment. I started with a basic Node.js app and ended up understanding key Docker concepts that I’m sharing below — explained in simple terms from a beginner’s point of view. Docker simplifies application development, deployment, and scaling by packaging your app along with its dependencies into containers. These containers run the same way in development, testing, or production — ensuring consistency across environments. First rule: Make sure Docker Desktop is running before executing any Docker commands. docker run -it ubuntu # Image docker container ls # List running containers docker container ls -a # List all containers (including stopped) docker start <conta…  ( 5 min )

Week 2 of Hustle2Grand is done, and it was intense. On Tuesday I launched LogicLore, my edtech platform that teaches computer science to kids through themed challenges. The product feels solid, but I didn’t market it enough — no users signed up. Definitely something I’ll need to improve soon. Then in just two days, I built and launched VibeFight, a launch arena for “vibecoded” projects. It got 140 visitors in the first 2 days, but only 3 submissions. I shared it on Reddit and got tons of feedback, which I summarised in a post here: Everyone said it was genius. No one used it. Medea ・ Jul 4 #webdev #vibecoding #javascript #learning Biggest takeaways: People lurk more than they interact Comments ≠ users Users need a reason to come back or take action (incentives, community, visibility, etc.) On top of that, I prelaunched VibePatch, a security audit agency for vibecoders. It offers manual website reviews before launch to catch common vulnerabilities. I priced it at £50 to start with, but no customers yet. Shipping fast is great, but without proper marketing or distribution, nobody shows up It’s easy to confuse interest with traction — validation needs action, not compliments Burnout is real. After pushing three projects in two weeks, I hit a wall I’m taking next week a bit slower. My plan: Revamp my portfolio and clean up all the projects List GameGift for sale — it's a strong idea, but someone else might market it better than I can No new launches — just maintenance, polish, and regrouping After that: I’ll fix VibeFight using the feedback I collected Try more targeted marketing for LogicLore, which I still believe can be a core income stream Push for my first customers with VibePatch and start exploring more of the cybersecurity space Still a long way to go before I hit £1,000, but each week I'm learning what actually works — and what doesn’t.

1. Introduction: Code Is Just the Starting Point When most people think about web development, they picture lines of code HTML, CSS, JavaScript, maybe a fancy framework or two. And sure, writing clean, efficient code matters. But that’s not the full picture anymore. The best developers today understand that their job goes far beyond syntax. It's not just about getting the code to run it’s about making sure that what you're building actually solves a real problem for real users. Whether it’s making a checkout process faster, improving performance on slow mobile networks, or just making a site easier to navigate for someone using a screen reader that’s the real challenge. Web development has evolved. We’re no longer just “website builders.” We’re problem solvers, user advocates, and system…  ( 7 min )

Introduction In the realm of DevOps, where speed and reliability are paramount, deployment strategies play a crucial role in ensuring seamless releases. One such strategy that has gained significant traction is Blue/Green Deployment. Blue/Green Deployment involves maintaining two identical production environments, one 'blue' and one 'green.' At any given time, only one environment serves live traffic while the other remains idle. This setup allows for smooth transitions during deployments without impacting end-users. By switching traffic between the blue and green environments, organizations can achieve zero downtime deployments. This ensures that users experience uninterrupted service during updates. In the event of issues post-deployment, rolling back changes is simplified in a Blue/Green setup. By directing traffic back to the stable environment, teams can quickly mitigate any issues. Utilize tools like Terraform or CloudFormation to define and provision infrastructure. This ensures consistency between the blue and green environments. resource "aws_instance" "example" { ami = "ami-0c55b159cbfafe1f0" instance_type = "t2.micro" } Implement automated testing to validate deployments in both environments. Tools like Selenium for UI testing and Jest for unit testing can streamline this process. describe('Calculator', () => { test('adds 1 + 2 to equal 3', () => { expect(sum(1, 2)).toBe(3); }); }); Blue/Green Deployment offers a strategic approach to deployment in DevOps, enabling organizations to release software with confidence and agility. By leveraging this methodology, teams can mitigate risks, ensure high availability, and deliver exceptional user experiences.  ( 3 min )

A Duet of Performance and Safety: Technical Analysis of Modern Web Frameworks As a third-year computer science student immersed in the world of computer science, my days are consumed by the logic of code and the allure of algorithms. However, while the ocean of theory is vast, it's the crashing waves of practice that truly test the truth. After participating in several campus projects and contributing to some open-source communities, I've increasingly felt that choosing the right development framework is crucial for a project's success, development efficiency, and ultimately, the user experience.

Building a rootless framework is difficult, but still Proton was built with a very intentional design choice: its components are allowed to return anything - from DOM Nodes, to primitives, and null/undefined. This flexibility is not a bug, but a feature. However, this freedom comes with sharp edges: when null is returned, no anchor is created, and the view replacement logic has nothing to latch onto. One of core goals of Proton is to eliminate the concept of "Root Components" entirely and embrace fully "Atomic Components" - meaning self-contained, relocatable, and behaviorally independent. For example: function Component() { setTimeout(() => this.view.set( Another layout ), 1_000) return Some layout ) const com…  ( 4 min )

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, CSS Art: Office Culture. For this CSS Art piece, I wanted to capture the essence of contemporary office culture where technology and personal elements blend to create a productive yet human workspace. My inspiration came from: The Digital Transformation - How modern offices revolve around technology with computers as the central hub of productivity *Developer Culture *- The ubiquitous coffee, mechanical keyboards, and coding environment Work-Life Balance - Personal touches like desk plants that bring nature into digital spaces Continuous Learning - The books representing ongoing skill development in tech Collaboration - Floating icons symbolizing communication, ideas, and teamwork I aimed to create a scene that resonates with today's hybrid work environment while celebrating the tools and rituals that define our office experiences. Live Demolink! Creating this CSS artwork was a journey of pure creative expression through code. I'd love to expand this project by: Adding interactive elements (e.g., turning on/off the monitor) Creating day/night cycle animations Developing additional office scenes (meeting rooms, break areas) Implementing a 3D perspective with CSS transforms Adding sound effects for a more immersive experience This project reminded me that CSS is not just a styling tool but a powerful medium for artistic expression. The modern office is more than just a physical space—it's an ecosystem of tools, rituals, and human connections that I've enjoyed representing through code.  ( 3 min )

When working with objects and arrays in JavaScript, developers often run into unexpected behavior because of how copies work. A major confusion is between shallow copy and deep copy. 🟠 What is a Shallow Copy? That’s what a shallow copy does. const original = { const shallow = { ...original }; console.log(original.skills.frontend); // Output: "Vue" ❌ 🟢 What is a Deep Copy? That’s a deep copy in JavaScript. const deep = JSON.parse(JSON.stringify(original)); Here, deep is fully independent — changes inside don’t affect the original.  ( 3 min )

Hi, I’m Shaheen Amjad, a full-stack web developer. I have more experience with back-end APIs, having two years of experience in both back-end and front-end, but I like APIs more. What do I need? The experience I’ve gained over the past two years has been in the projects I’ve created, which are huge. I’ve also created a project similar to Shopify ( it was my first project btw ). I’ve created many projects, but why? Because no one has interviewed me. I’ve also tried freelancing, but no one has contacted me! I’m 16 years old, and I only have internet access and a laptop (4GB RAM, Intel Core i3 processor). I don’t have any money, and I want to profit from the things I love, just like the guys I found on YouTube when they publish their SaaS projects. What I need from you all is for you to give me your requests, your ideas, everything. I’m really exhausted from looking for opportunities and ideas. I’ve built three APIs, and they haven’t worked. I’ve marketed them on social media, but no one has shown interest. So, I’m responsible for the requests, because I don’t know what needs to be solved. So, I said I can come here and ask people for requests or needs to create projects. Whatever your specialty… please give me some ideas. If you’re a developer, please provide me with any ideas you can think of. If you have an idea, you don’t need a database. That would be even better because I don’t have any money to buy one. thanks for everyone -shaheen amjed  ( 3 min )

1. What is Virtualization? Virtualization is the process of creating a virtual (rather than physical) version of something, such as a server, a desktop, a storage device, an operating system, or network resources. It allows multiple virtual systems to run on a single physical system, maximizing hardware efficiency and flexibility. Key Concepts: Virtual Machines (VMs): Software-based emulations of physical computers. Each VM runs its own OS and applications. Hypervisor: Software that enables virtualization by managing and allocating resources to VMs. There are two types: Type 1 (bare-metal): Runs directly on hardware (e.g., Microsoft Hyper-V, VMware ESXi). Type 2 (hosted): Runs on a host OS (e.g., VMware Workstation, VirtualBox). Resource Sharing: Virtualization allows CPU, memory, a…  ( 4 min )

In the construction industry, timing and budgeting are everything. But there's one surprisingly frustrating issue that affects millions of builders, contractors, and homeowners across countries like India and Pakistan — there’s no simple way to check updated cement prices online. Yes, you read that right. If you’ve ever tried to build a home or manage a construction project, you’ve probably noticed how cement prices vary wildly from region to region, and even between local dealers in the same city. You’ll find prices on WhatsApp, through word of mouth, or by calling up suppliers one by one — but rarely in a structured, updated, and trustworthy format. This gave me an idea: “What if I built a tool that simply tracked cement prices in one place — fast, clean, and easy to use?” As someone wit…  ( 6 min )

Welcome to another Sunday Blog on System Design. don’ts to keep in mind when designing a system using The Method. Here are the rules we've already summarized. As I often say: Learn the rules, follow the rules — and only once you're good at it, should you even think about bending them. I suggest going through the last two articles to fully grasp the ideas discussed here: Part 1 | Part 2 Avoid functional decomposition (what we were doing in universities), and remember: a good system design speaks — through how components interact. The client should not be the core business. Let the client be the client — not the system. Decompose based on volatility — list the areas of volatility. There is rarely a one-to-one mapping between a volatility area and a component. List the requirements, then iden…  ( 7 min )

📝 This is cross-posted from my personal site - https://chrisdavies.dev . A common adage for any developer choosing a database technology is "just use Postgres". While this advice remains well-intentioned, it deserves a fresh look in 2025. Thanks to a wave of recent innovations and acquisitions, PostgreSQL providers now resemble JavaScript frameworks of the 2010s - there’s seemingly a new one to consider every six months. Just choosing PostgreSQL isn’t enough anymore - there is an entirely new decision tree to follow before you can launch a system. 🌳 TL;DR: The answer to "Which one do I choose?" is always "It depends", but this post signposts exactly what those deciding factors are. ⚖️ Postgres uses an elephant as its mascot.

🚧 Scope Will Creep - Your Job Is to Tame It, Not Eliminate It No matter how well you plan, scope creep is inevitable. Saying “No” can damage trust. Saying “Yes” to everything can break the timeline. 🔧 Instead of pushing back, say: “That’s a great feature; let’s log it under Phase 2 so we can stay on track for the current delivery.” This one sentence helps: 🔑 Best Practices to Stay in Control 📋 Start with a clear Scope Statement - Define what’s included, what’s excluded, and what success looks like. Use a simple Work Breakdown Structure (WBS). 👥 Involve stakeholders early & often - Don’t assume. Confirm. Regular check-ins help align expectations before they turn into surprises. 🧾 Use a formal Change Request process - Every new idea should pass through effort, time, and cost filters. Approve wisely. 🗂️ Maintain a “Parking Lot” or Phase 2 Backlog - A space for great-but-not-now ideas. It shows you’re listening — while protecting current goals. 📊 Track progress against the scope baseline - Weekly updates reveal scope drift early. Compare planned vs. actual often. 🚨 Educate gently on scope creep risks - Sometimes people don’t realize the impact. A simple heads-up like “this might delay things” makes a big difference. ⏱️ Timebox when possible - Short sprints and fixed milestones help keep momentum and clarity. 💡 Final Thought Scope creep doesn’t mean chaos. The key is to channel that energy without losing direction. You’re not here to block ideas - but to guide them. Be the compass 🧭 - keep the course clear, focused, and flexible.  ( 3 min )

AI Menu Visualizer: Bringing Restaurant Menus to Life This post is my submission for DEV Education Track: Build Apps with Google AI Studio. I created an AI Menu Visualizer that transforms static restaurant menus into vibrant visual experiences. Using Google's Gemini AI, the app can analyze both English and Chinese menu text, identify dish names, and generate photorealistic images for each dish. The key prompts include menu text extraction with structured JSON output and carefully crafted image generation prompts for appetizing, professional food photography. Code is here: [https://github.com/williamhatch/ai-menu-visualizer] Key Features: Bilingual menu support (English & Chinese) Real-time dish detection and image generation Modern, responsive UI with Tailwind CSS Progress tracking for multi-dish menus Error handling and graceful fallbacks Building with Google AI Studio and Gemini was surprisingly intuitive. Key takeaways: Multimodal Power: Gemini's ability to understand both text and images made menu analysis seamless. The model handles bilingual content exceptionally well. Structured Output: Using the responseMimeType: "application/json" config ensures clean, parseable responses - crucial for production applications. Image Generation Quality: Gemini's Imagen model produces consistently high-quality food photography, though prompting requires careful crafting for best results. Developer Experience: The @google/genai SDK is well-documented and TypeScript-friendly, making integration straightforward. The most challenging aspect was optimizing the image generation prompts to produce consistent, appetizing results across diverse cuisine types. The solution was to standardize the prompt structure with specific photography-focused language. This project demonstrates how AI can enhance real-world dining experiences by bridging the gap between text menus and visual presentation.  ( 3 min )

My Experience The tricky bit was keeping the meme tone light and not making it sound like a machine wrote it. I had to tweak the prompt a few times — even added examples like “When you realize it's Monday again” to give the AI a vibe to follow. Also, Streamlit made the UI part painless. I didn’t touch HTML or CSS — just a few lines and I had a working web app. Screenshots -  ( 3 min )

Not sure if this will resonate with others, but something weirdly powerful happened to me recently. I was feeling stuck — not in terms of code, but direction. I’d fix a bug, build a small feature, help someone, learn something — and then forget it the next week. It all felt like I wasn’t making progress, even though I was. Then I started logging. Like, really small entries: "🔥 fixed weird async bug after 2 hrs—learned about event loop.” “I don’t write code — I plant bugs and call it ‘feature growth’ 🙃.” “🚧 messed up prod config — learned to double check .envs lol” Nothing fancy. Just me and my thoughts. Sometimes code-related, sometimes personal growth. I used a platform called Devmate — it gives a kind of "command-line journal" for devs. It felt like a private logbook — but if I wanted, I could also share it with others. And it slowly started showing stats, clone count, logs per day, and even latency time (I’m a sucker for metrics 😅). What changed? I saw my growth clearly. I felt more accountable, even on bad days. I now have a timeline of my effort, not just achievements. Looking back, I realized how far I’ve actually come. And weirdly... I stopped comparing myself to others. I’m not trying to "sell" anything. I just wanted to share this with other devs who might be feeling like they’re not doing enough—when in reality, they’re doing a LOT. They just aren’t capturing it. Anyway, if you feel like giving it a try: ➡️ https://devmate.space (it’s free and lightweight and honestly feels kind of calming.) Curious—does anyone else keep a dev journal or log?

Imagine teaching a group of smart robots to play a team game — but first, they need to remember the rules and their roles. That’s what AutoGen does with State and Memory Imagine you have a bunch of talking robots (these are called agents in AutoGen). Each robot has a job to do—like answering questions, solving puzzles, or writing stories. But how do these robots remember what’s going on in the game? That’s where state and memory come in! Memory is like a robot’s notebook. So next time you ask it something, it can look back at the notebook and remember what you were talking about. 💡 Memory helps robots not forget! State is like the robot’s current mood or job. The state tells the robot: What it should do next What its goal is What’s already done 💡 State helps robots stay focused and not get confused! Let’s say you have: Robot A: Good at explaining things Robot B: Good at writing code Robot C: Asks the questions (that’s you!) All three robots talk to each other, and they share the same notebook (memory). work like a team! AutoGen is like the game master: It gives each robot a job (state) It gives them a shared notebook (memory) It helps them talk, think, and solve things together Why Should We Care? Without memory and state: Robots forget everything—like a goldfish! They repeat the same things They don’t work well as a team With memory and state: Robots remember what you said before They stay focused They finish tasks smarter and faster I love breaking down complex topics into simple, easy-to-understand explanations so everyone can follow along.

The AI integration possibilities are moving towards a fundamental shift. While APIs have served as the backbone of software integration for decades, a new protocol is emerging that promises to transform how AI systems interact with external tools and data sources. Enter the Model Context Protocol (MCP)—Anthropic's open-source standard that's redefining the boundaries between AI models and the applications they serve. For years, developers have relied on APIs to connect disparate systems. The RESTful revolution democratized software integration, enabling everything from mobile apps to enterprise systems to communicate seamlessly. However, when it comes to AI language models, traditional APIs reveal critical limitations. Consider a typical scenario: A developer wants to give an AI assistant …  ( 8 min )

Distance-aware queries are a core feature for modern apps—whether you're matching riders and drivers, showing events around a user, or surfacing the nearest warehouses for same-day delivery. The fastest, most accurate way to deliver those results is to compute great-circle distance inside your SQL engine with the Haversine formula, then let Eloquent give you a fluent, testable API. Mathematically sound. Haversine treats Earth as a sphere, producing realistic distances at planetary scale without the overhead of full ellipsoidal calculations. Pushes work to the DB. The heavy trig runs where your data already lives, slicing result sets before PHP ever sees them. Vendor-agnostic. Works in MySQL, MariaDB, Postgres, SQL Server—anything that supports basic trig functions. The Haversine formula gi…  ( 5 min )

Handling multi‑gigabyte uploads in a stateless app is painful: TCP throughput caps slow single‑request uploads, server disks fill, and Lambda containers vanish between requests. Modern teams therefore push the heavy bits straight from the browser to Amazon S3. S3M—a lean wrapper around S3's multipart and presigned‑URL APIs—removes the boilerplate. S3M works with any JavaScript front‑end, but in this post I'll give you some examples using Vue so you can see the flow end‑to‑end without locking you into a specific framework. Amazon limits a single PUT to 5 GB. Multipart uploads slice the object, let slices fly in parallel, and re‑assemble the completed object inside S3. Presigned URLs add a time‑boxed signature, allowing the browser to upload directly to S3 while your API remains stateless an…  ( 5 min )

As a junior student learning web development, I discovered that choosing a framework isn't just about selecting a set of APIs—it's about choosing an ecosystem.

Leveling Up Terraform Notifications: A Deep Dive into AWS CodeStar Notifications Infrastructure as code (IaC) has fundamentally changed how we manage cloud resources. However, simply applying code doesn’t guarantee operational excellence. Knowing when a Terraform apply succeeds, fails, or drifts is critical for maintaining stability and responding to incidents. Traditional methods – relying on CI/CD pipeline logs or manual checks – are often insufficient, especially in complex, multi-team environments. AWS CodeStar Notifications fills this gap, providing a robust, event-driven notification system directly integrated with Terraform workflows. This isn’t just about alerting; it’s about building observable infrastructure. It fits squarely within a platform engineering stack, providing a cru…  ( 7 min )

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. Who doesn't love Pokemon and the endless joys in playing with Trading card games. There are tons of Pokemon card makers available over the internet but it lacks of bit of imagination. Hence I have created a fun app for the kids to create their own Pokemon card maker with powerful AI features. As we all know ,the app creation depends upon our imagination especially your prompting skills. I have created a basic prompt and used Google Gemini to enhance the prompting which shown below "Create a full-featured Pokémon Card Maker App that enables users to create, customize, and share their own Pokémon-style trading cards. This app should include both official Pokémon characters and the ability to create custom imaginary Pokémon with rich detail. It must be engaging, fun, and visually aligned with the Pokémon universe aesthetics."

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. A (long) while back, I had this idea for a startup. I wanted to build a personal writing assistant to help fiction writers. This was in the days before Generative AI. Once Generative AI came about, I knew this idea would evolve. I documented this concept on a product page I developed years ago. It was time to take AI for a spin and see what it would come up with. My first thought was to give it a webpage with the product features and see what it would do. I was a bit skeptical it would work, and...it didn't. It created something completely unrelated to the product page I created. So, I would need to start simpler. Before starting this project, I had already tried creating a character generator with Googl…  ( 5 min )

Hey problem solvers! 🧠 Today we’re tackling an interesting design-based problem — where you don’t just compute once, but need to efficiently add values and count pair sums across two arrays. This one blends hash maps with careful indexing to keep operations optimal. Let’s break down how to structure the FindSumPairs class for the win! 🔧 You are given two arrays nums1 and nums2. You must: Implement a class FindSumPairs that supports two operations: add(index, val): Add val to nums2[index]. count(tot): Count how many pairs (i, j) exist such that nums1[i] + nums2[j] == tot. The class should efficiently handle many such operations. We fix nums1 as a reference array. We store a frequency map for nums2 so that count(tot) can be done in O(n) instead of O(n²). When add(index, val) is called, we …  ( 5 min )

AI is everywhere. But where it runs — and where your data flows — matters more than most teams realize. There are three main ways to deploy AI: On-premises AI (self-hosted, full control) Cloud-based AI (platforms like AWS, Azure, GCP) AI via third-party tools (like Notion AI, Canva AI, Make, etc.) Each option has trade-offs in security, cost, scalability, and control. The right choice depends on your infrastructure — and how much ownership you want over the stack. What it is: Running AI models locally on your own servers — either physical or private cloud. Think of hosting LLMs like LLaMA or Mistral on self-managed machines.

Data Isn’t Just Power — It’s Liability Too Why Your Dataflow Matters More Than Ever in the Age of AI In 2025, “data is the new oil” is no longer just a cliché — it’s the currency of your business logic, automation, decision-making, and competitive edge. But while the buzz around AI and cloud tooling keeps rising, one critical component remains dangerously overlooked: your internal dataflow. Who has access? Where is it stored? When is it enriched, synced, analyzed — and by whom? And most importantly: When is it safe to run AI on it? And where? A dataflow is more than a series of spreadsheets and dashboards. It’s the end-to-end chain of how data enters your business, moves between systems, gets enriched, and ends up in tools — from CRMs to reports to AI agents. An effective dataflow s…  ( 5 min )

Introduction Both C23 and C++23 added the unreachable() and std::unreachable() functions, respectively, that insert undefined behavior into your program. (If you don’t know what undefined behavior is, you should definitely read that article first.) Ordinarily, undefined behavior should be avoided at all costs. So why does unreachable() exist and when would you ever want to use it? Its name gives a hint: it tells both compilers and programmers that the line of code on which unreachable is “called” is never actually called. What use is that? It allows you to: Suppress warnings. Perform a bit of optimization. It can do those things because the compiler is allowed to assume that undefined behavior never happens. It’s probably easiest to explain how unreachable() can be used to suppress …  ( 5 min )

In certain scenarios, we need to initialize some resources, such as singleton objects, configurations, etc. There are multiple ways to implement resource initialization, such as defining package-level variables, initializing them in the init function, or in the main function. All three approaches can ensure concurrency safety and complete resource initialization when the program starts. However, sometimes we prefer to use lazy initialization, where resources are only initialized when they are truly needed. This requires concurrency safety, and in such cases, Go's sync.Once provides an elegant and thread-safe solution. This article introduces sync.Once. sync.Once is a synchronization primitive in Go that ensures a specific operation or function is executed only once in a concurrent environm…  ( 7 min )

Looking back, I’ve seen many merchants and partners go through the journey from Magento 1 to Magento 2 (Adobe Commerce), including myself. Now, we’re entering the next evolution, Adobe Commerce as a Cloud Service (ACCS). Each wave of change brought something new, but also taught us something valuable. And while it’s tempting to compare these transitions as just “technical upgrades,” the reality is that each one reshapes how we think and build ecommerce solutions. When Magento 2 launched, it came with real improvements, better performance, modern APIs, stronger security, a new SLA for support, and security compliance from Adobe. However, it wasn’t an overnight switch, mainly because we could leverage the upgrade opportunity to revisit some implementation points and reduce costs, while also …  ( 5 min )

Understanding "learn resume" for Beginners Have you ever started learning a new programming language and felt overwhelmed by all the concepts? Or maybe you've built a small project and aren't sure how to show it off to potential employers? That's where the idea of a "learn resume" comes in! It's a way to track your progress, demonstrate your skills, and build confidence as you learn to code. This is super important, especially when you're starting out and don't have a lot of professional experience. Interviewers love to see what you've been actively learning and building.

What Is Meta-Learning? Meta-learning — often called “learning to learn” — is the idea that an AI model can learn not just from data, but from the process of learning across multiple tasks. Think of it like this: Traditional ML: "Here's a task — learn it well." Meta-learning: "Here’s a bunch of tasks — figure out how to learn any new one quickly." It’s especially useful in situations where data is scarce or new tasks keep popping up (like personalized recommendations, robotics, or medical diagnosis). Few-shot learning is one of meta-learning's most powerful applications. It means your model can generalize to new classes with only a few labeled examples — sometimes just one or two per class. Meta-learning makes that possible by training models to adapt fast, rather than memorizing everyth…  ( 5 min )

A week ago, an interviewer asked me: Why do we need to manage state in a frontend application? Why can’t HTTP handle it for us? There can be multiple answers to this, but the simplest one is: HTTP is a stateless protocol. Each HTTP request is independent. The server doesn’t know anything about previous requests. Why So? Can’t We Make HTTP Stateful? Why Exactly? 1. Scalability When your application grows, you no longer rely on just one server. But because it’s stateless, any server can handle any request. 2. Simplicity This means: No need to track sessions or store user-specific context. GET /user-profile The server does: Validates token Fetches user info Responds No memory of this is retained after the response 3. Performance Stateful systems usually need to keep track of: User sessions…  ( 4 min )

About three months ago, I started my journey with Ansible, a configuration and Infrastructure as Code (IaC) tool used by over 20,000 companies. There were some genuinely great things about Ansible that made it enjoyable to work with: Push-based: I write the config, and it just goes over SSH. No need for a big control plane or cloud API. Agentless: No weird daemons to install on every server. Just SSH and vibes. Collections: A whole ecosystem of plugins for AWS, Docker, Kubernetes — you name it. But the problems started early.

If AI can write your blog post, your LinkedIn update, and even your product documentation… why bother learning to write at all? It’s a fair question, and one I asked myself before writing this blog.

The idea came from my own workflow writing search-optimized content, where I often need to analyze how competitors position themselves in Google's sponsored results. The problem is that these ads — although rich in copywriting, links, persuasive hooks, and keywords — disappear quickly. Just by refreshing the search or waiting a few minutes, the same ad may no longer appear. This makes analysis and later study difficult. SideSave solves this by saving ads with title, link, snippet, and a clear visual marker that it's a sponsored result. How I Used Runner H I used Runner H as a tool to…  ( 4 min )

Software testing is one of those jobs where the frustrations pile up so fast, it feels endless. You’re on a deadline, requirements shift every hour, documentation is incomplete, and the line between manual and automated testing blurs. And if you’re in QA, you’ve probably heard it all: “QA is the bottleneck,” or worse, “QA is just a cost center.” These gripes aren’t just personal venting on Reddit—they’re the reality for many QA teams worldwide. A recent Reddit thread asked testers what daily QA pain points grind their gears the most. The responses are brutally honest: constant scope creep with frozen deadlines, flaky test automation that wastes time, unclear business requirements, and leadership that underestimates QA’s impact. One QA wrote, “Requirement and scope changes every 5 minutes …  ( 5 min )

AWS Certificate Manager (ACM) simplifies SSL/TLS certificate management for securing web applications. When using Amazon Route 53 as your DNS provider, generating a certificate is seamless. However, if you use a third-party DNS provider (e.g., GoDaddy, Namecheap, or Cloudflare), you may encounter a common error during certificate validation: Error: "One or more domain names have failed validation due to a Certificate Authority Authorization (CAA) error." This error occurs because ACM requires specific DNS records to verify domain ownership, and third-party DNS providers need manual configuration to allow Amazon’s Certificate Authority (CA) to issue the certificate. In this guide, we’ll walk you through troubleshooting and resolving this issue step-by-step. Access to your third-party DNS provider’s management console. Step 1: Understand the CAA Error Step 2: Add CAA Records in Your DNS Provider Save the changes. (Note: DNS propagation may take a few minutes to hours, depending on your provider.) Step 3: Request a New Certificate in AWS ACM Select Request a public certificate and click Next. Enter your Fully Qualified Domain Name (FQDN) (e.g., amalcloud.com or www.amalcloud.com). Optionally, click Add another name to this certificate to include alternative names (e.g., *.amalcloud.com for wildcard certificates). Return to your DNS provider’s DNS management console. Step 5: Wait for Validation dig CAA example.com Ensure amazonaws.com and amazon.com appear in the results. Incorrect CAA record syntax (e.g., missing 0 issue or quotes). By adding the required CAA and CNAME records to your third-party DNS provider, you can resolve the AWS ACM CAA error and successfully issue a certificate. This process ensures your domain is validated and your certificate is ready for use with AWS services. If you encounter persistent issues, double-check your DNS records, consult your DNS provider’s documentation, or contact AWS Support.  ( 5 min )

Intro Nowadays complex web apps that feature rich, dynamic UIs are taken for granted. And it's not surprising — the internet has come a long way since its inception. Initially, the internet wasn't built to support such dynamic and complex web apps. It was conceived to be a collection of HTML pages, linking to one another to form the concept of "web" that contains information. Everything was largely built around the so-called request/response paradigm of HTTP. A client loads up a page and then nothing happens until the user clicks and navigates to the next page. Around 2005, AJAX was introduced and a lot of people started to explore the possibilities of making connections between a client and а server bidirectional. Still, all HTTP communication was steered by the client, which required u…  ( 13 min )

Who your friends are says a lot about you. And in our ever-more digital world, public knowledge of who they are may be a major security risk to you. This risk has been spotlighted once again with the recent scandal of US national security adviser Michael Waltz’s exposed Venmo Friends List. Venmo, a popular American mobile payment app owned by PayPal, allows the user to sync contacts from their phones directly into the app as “friends”. These friends then populate the user's "Friends List" within the app, letting the user easily transact with their existing contacts without asking for their Venmo accounts. While it may seem common and user-friendly for apps to import contacts from your phone, the social media aspect of Venmo makes this feature dangerous because your Friends List, i.e. all y…  ( 6 min )

mock interview is a simulated job interview designed to mirror real interview scenarios. It provides candidates with a platform to practice their responses, refine their communication skills, and receive constructive feedback in a risk-free environment. This preparatory exercise is instrumental in building confidence and enhancing performance in actual interviews The primary purpose of a mock interview is to prepare candidates for real-life interview situations. It allows individuals to: Gain familiarity with common interview questions and formats. Receive immediate feedback on their responses and demeanor. Identify areas of improvement in both verbal and non-verbal communication. Develop effective strategies for articulating thoughts and experiences. By simulating the interview environment, candidates can reduce anxiety, improve their presentation skills, and approach actual interviews with greater confidence Regular practice through mock interviews helps in alleviating nervousness and building self-assurance. Candidates become more comfortable articulating their thoughts, leading to a more confident demeanor during actual interviews. Mock interviews provide an opportunity to refine both verbal and non-verbal communication. Participants can work on aspects like tone, clarity, body language, and eye contact, ensuring a more polished presentation.  ( 3 min )

Introduction Every day of developer's career, interaction with a programming language is the way to compile and run applications. If no errors found, it just executes and performs its job. Sometimes, new to intermediate developers have asked themselves at least one of the following questions: What happens when code is compiled? is CPU able to understand C# code? How variables, objects are handled in memory? What does "Run" mean? Questions before are completely valid. To answer them, .NET has a powerful platform doing so much work behind the scenes: The CLR. .NET CLR (Common Language Runtime) is the engine of the .NET environment where C# code is compiled and executed. Every application built on ASP.NET Core MVC, WinForms, MAUI, etc, needs a runtime to execute. It supports different progr…  ( 5 min )

Docker containers are lightweight, portable, and awesome for deploying apps. But let’s be real—security is a big deal, and encryption is a key piece of keeping your containers safe. Whether it’s sensitive data, API keys, or user info, you don’t want it floating around unencrypted. This post dives into encrypting Docker containers, focusing on practical steps, real-world examples, and tools you can use to secure your setup. We’ll cover encrypting data at rest, in transit, and even during runtime, with code you can actually run. Containers are great, but they’re not bulletproof. If someone gets access to your host or a container’s filesystem, unencrypted data is an easy grab. Plus, if you’re moving data between containers or external services, it’s vulnerable without encryption. Encryption p…  ( 8 min )

You know, as Senior Software Engineers, our roles naturally evolve. We start writing code, but soon we are architects, mentors, strategists. We are leading tech stack modernizations or diving deep into optimizing sprawling monorepos. We design scalable solutions, like the GraphQL federated graphs that boosted our data architecture efficiency. It is all about operating at a higher altitude, right? Thinking big picture: system health, developer experience, long-term maintainability for millions of customers. But here is a little secret: amidst all these grand designs, it is incredibly easy to dismiss the "grunt work."

🧠 Context Today, I stepped back from building features to refactor and clarify the data relationships between the major entities in our system — Workspaces, Cases, Documents, Users, Tags, and Calendar Events. 📦 What I Did Simplified Relationships At first, we had awkward relationships like: Case having both workspaceId and a nested workspace reference, Document storing redundant workspace references already tied through Case. I cleaned this up using Prisma relations. Now, each document belongs to a case, and the case belongs to a workspace. This means fewer joins, less chance of inconsistency, and clearer logic in queries. prisma model Workspace { id String @id @default(uuid()) name String cases Case[] } model Case { id String @id @default(uuid()) title String workspace Workspace @relation(fields: [workspaceId], references: [id]) workspaceId String documents Document[] } model Document { id String @id @default(uuid()) title String case Case @relation(fields: [caseId], references: [id]) caseId String } Improved Naming Conventions Added Indexes for Performance prisma @@index([workspaceId]) @@index([caseId]) ⚠️ Lessons Learned You don’t need to get your schema perfect on Day 1. Design clarity = easier maintenance and faster development. Refactoring schemas early saves hours later. A simple, normalized structure beats clever tricks. 🔍 Bonus Debug Tip npx prisma migrate reset Just remember to back up your seed data first! ❓Question Let me know your approach!

Table of Contents Introduction Why chunking Why contextual chunking Why fixed-size chunking is insufficient How to implement contextual chunking Docling Google Gemini 2.5 Pro/Flash Conclusion In many enterprise settings, we often have documents which are highly structured and nicely formatted. There is often a hierarchical approach in how the information is structured. For example, there is usually a content page, and relevant information are often grouped by sections. The section numbers are also in running order, and often follow a certain convention, e.g. "d.d.d Header". When creating RAG for thousands of such documents, chunking is often necessary so that when queried, the chunks are of manageable length to be passed to LLMs as context. Contextual chunking has significant advantag…  ( 51 min )

A reflection on benfits of full text OCRization and how it becomes handly with LLM enables applications. Full Optical Character Recognition (OCR) of a document like a PDF offers a wide range of benefits, transforming static, image-based files into dynamic, searchable, and editable content. Here are the key advantages: Searchability: This is arguably the most significant benefit. Without OCR, a scanned PDF is essentially just an image, and you can’t search for specific words or phrases within it. Full OCR converts the image of text into actual, machine-readable text, allowing you to easily search for keywords, names, dates, or any other information. This is incredibly useful for large documents, archives, and research. Editability: Once OCR is applied, the text within the PDF becomes edita…  ( 39 min )

Responsive design isn’t a luxury anymore—it’s a necessity. In 2025, with countless devices and screen sizes, building flexible layouts that adapt beautifully is table stakes for any frontend developer. But which layout technique should you use? CSS Grid, Flexbox, or the new player in town—Container Queries? In this post, I’ll walk you through the differences, strengths, and ideal use cases of each. We'll even look at examples where they shine, and when to combine them. 🎯 1. CSS Flexbox: For One-Dimensional Layouts ✅ Pros Great control over spacing and alignment Powerful with gap, justify-content, and align-items 🛑 Limitations 💡 Example: Horizontal navigation bar .nav { display: flex; justify-content: space-between; align-items: center; } 🧱 2. CSS Grid: For Two-Dimensional Layouts ✅ Pros Supports named lines, grid areas, and implicit/explicit rows Cleaner markup than deeply nested Flexboxes 🛑 Limitations Can be overkill for simpler UI 💡 Example: Responsive 3-column layout .grid-container { display: grid; grid-template-columns: repeat(auto-fit, minmax(200px, 1fr)); gap: 1rem; } 🔍 3. Container Queries: The Future of Truly Modular Components ✅ Pros Perfect for design systems Solves the "component breaks in different layouts" problem 🛑 Limitations Requires enabling contain and setting container type 💡 Example: Card layout adapting to container size .card { container-type: inline-size; } @container (min-width: 500px) { .card { flex-direction: row; } } 🛠️ When to Use What? Use Grid for the page layout Flexbox inside each section/card Container Queries to make each card responsive on its own Understanding how to use CSS Grid, Flexbox, and Container Queries together helps you build scalable, modular, and beautiful layouts. ✍️ Over to You Have you started using container queries in your projects?

Image generated using DALL-E As I start my next college class, Introduction to Information Security, I’ve had a wake-up call: Most people—even those who use the internet every day—know almost nothing about their own home Wi-Fi. They get internet service from a provider, the installer hands them a router, and they just…start browsing. The password? Usually the default one printed on the sticker—never changed, never thought about again. Reading through my classmates’ responses this week, I saw a pattern: “I didn’t realize how much I was lacking when it comes to securing my time online.” And it hit me: If adults don’t understand the basics of the hardware and networks they rely on, how can we expect our kids to grow up safe and smart online? It’s not enough to teach kids how to avoid suspicious links or choose strong passwords. We need to teach them: How a router works Why you should change default passwords What encryption is and why it matters How devices connect to Wi-Fi and share data Understanding the hardware and connections gives them power—so they don’t just use tech blindly, but know what’s happening under the hood. Our kids aren’t just watching YouTube and doing homework online—they’re building habits that will stick with them for life. If we teach them now how to: Secure their devices Recognize insecure networks Question the default settings they’re given We’re giving them tools to protect themselves in an increasingly connected world. Did you grow up learning how your own Wi-Fi or devices worked? What have you taught your kids (or wish you had) about tech safety? How can we make understanding the basics of our devices as normal as teaching kids how to ride a bike? If we want the next generation to thrive online, we need to start by teaching them what’s happening offline—right at home.  ( 4 min )

This is why proactive measures like vulnerability scanning, penetration testing, and continuous monitoring are no longer optional—they are essential. Why Cybersecurity Should Be Your Priority Financial damage is real. Data breaches cost businesses millions every year—not just in recovery expenses but also in lost customer trust.

Today took a first step towards learning Data Science. In Python, we learned about few methods like print(),id() etc, and about Mutable & Immutable variable types. Method Print() Syntax: Method id() Syntax: Variable always refers to the memory reference and not to the value. Variable type like Integer, float and Boolean are of Immutable Type. In Immutable variable type value cant be changed and only one instance of memory is created but shall be referred to with n number of variables. Variable types like Strings, Lists are Mutable, meaning could be changed. Data structure type List: Syntax: As mentioned above in the list data structure a list of values could be stored in an order and could be referred to a particular value by indexing, index 0 refers to the first value in the List and progressively 1,2,3 etc refers to the next consecutive values.

Building a React component library that puts developer experience and customization first Picture this: You're building a beautiful accordion component for your app. You want to add some smooth GSAP animations to make it feel premium. You're using shadcn/ui, which is fantastic, but then you hit a wall. The accordion component uses Radix UI primitives under the hood. These primitives are great for accessibility and basic functionality, but they're black boxes. You can't modify their internal behavior. You can't add complex animations. You can't change how they handle state transitions. I needed my accordion to have sophisticated GSAP animations with custom easing, staggered reveals, and precise timing control. But the Radix primitives were fighting me every step of the way. That's when I re…  ( 6 min )

Hi everyone! 👋 Welcome to my very first online article! 😄 This is actually my first time writing a technical post, so please bear with me if it’s not perfect. I'm open to feedback and discussion — feel free to drop your thoughts in the comments to keep me motivated and excited to share more! This article is inspired by a recent task I received from my team at work. We're currently working on a JavaScript-based project using Nuxt.js, and I was asked to research date manipulation libraries. We had previously used Moment.js, but recently I noticed several articles and developer communities comparing it to Day.js. Some even titled their posts "Is Moment.js Dead?" or "Why You Should Switch to Day.js." That got me curious — if the functionality is similar, why is there so much talk about swi…  ( 4 min )
